    Rear deck ideas

    Please share pictures of your rear deck.
    I am planing on redoing the rear deck along with replacing the fuel sending unit. I installed 2 Sony speakers but the rear deck has been modified too many times and the vinyl is in poor shape. I have 2 original speaker covers and plan to make it stock ish but with 2 speakers.

    Thanks in advance.

    I think the rear deck only came with one speaker. Mine was cut out for 2 speakers. If it wasn't so darn cold, I'd pull the cover off and take a couple of pictures for you. I'm sitting at 29 degrees now, I will try later today to get pictures. Take care, Jarrell

    Hence the stock ish with 2 speakers. I will also be taking out the seats to do this and the fuel sending unit. I also need to install the seat belt that I have so far left out. Livin on the edge.

    Here's my rear deck. I created a sculpted foam deck contour, covered in auto carpet, which helped to slightly elevate the Corvette, roof top brake light. The Opel insignia was an embellishment. My speakers reside in the vertical divider panel, behind the cargo platform.

    Here are some interior shots of mine. I added 6x9's on risers I made out of plywood and bondo to the rear deck so the spare tire can fit in (two holes were already cut in the rear deck for the speakers) and 5.25" component mids to the bottom section. The tweeters are in the front on vinyl-wrapped aluminum holders I made. The rear deck is a lockable flipper made out of marine plywood an covered in a thin foam with vinyl wrapping and connected with a piano hinge. I added an extra Opel emblem on the flipper to line up with the front emblem when looking from the front through the interior of the car.

    I got rid of my rear deck entirely and have 6x9's pointed directly at my skull. I put everything on strip hinges and made storage compartments for stuff like beer. Last year I put a subwoofer back there.

    Several owners have commented that replacing rear vinyl cover using plywood with acoustic foam will quiet the GT noise level.

    Insulation on wood spare tire structure shelve to reduce road noise:

    I found that Dynamat Insulation the bottom of Tire Shelve has reduced all the road noise, and made the stereo sound better

    Good information Lindsay and Gordo nice looking rear deck. Love the special storage compartments
    What happens if you need to change the tire or do you call a tow, roadside assistance or roll the dice

    I'm looking at doing something kind of similar, but was planning on removing the support brace between the wheel wells with tube steel and tying in into my cage. did you add any support back when you cut that horizontal base? My plan was to go essentially from that seam under the rear window and go straight down to just behind the rear shock mounts with aluminum plate, which would keep me clear for adding support to the shock mount area for my cage bars to mount to... I have 6x9's and sound mat. I guess the question I don't have an answer to is... How necessary is that rear support brace that lies between the rear wheel wells...? My GT is not going to be a daily, but rather a Sunday driver and autocross runner every now and then.

    I have a wood construction back there. Can't weld and I'm trained in wood working, so it was the logical choice. I'll have to wait until I'm home from work to access my pics and post some.

    No spare tire, just a can of fix-a-flat. I buy premium all season high traction tires and avoid roads/places that can cause flats, so my chances of getting flats is very low.

    That's an excellent idea and I'm sure that would be more than enough strengthening to resist torsional stresses and would probably be even stronger and more effective than that flimsy crossbar.

    Excellent. Question, what do you do if you should want to change/upgrade shocks? Jarrell

    The plan is to stay behind the shock mounts (to the rear) with the fixed metal panel. The support running from side to side in the unibody where the shocks actually mount will be reinforced with plating and tied into the cage. shock mounts will still be accessible. Probably going to carpet over or create a false panel kind of how Gordo has. Something removable, just a cover to hide all of that stuff.

    Except for the reshaped luggage shelf piece, the entire assembly rests on the spare tire shelf ledges and doesn't touch the body anywhere, except slightly, on purpose, at the arc-shaped piece below the window. Sitting on those spare tire shelf ledges and my custom tank being a bit less-tall than an oem one, there's a 1/2"-3/4" gap between the wood and the tank. No felt pads needed to dampen vibration. The curving sort of frame rail thing that the shocks bolt into is below the top of the tank by several inches, so there's plenty of room to access the shock bolt/nuts, as seen here:

    Tank swap 005.JPG

    I can remove the piece that covers the filler neck and I've got a piece of sheet metal over a hole above the fuel sender unit, so that I can access those items as needed:

    Filler neck redo (1).jpg

    And, worse case scenario, I CAN remove the whole thing in about an hour, like I did when I swapped the aluminum tank from my Red Baron car into the GTX, but it's messy:

    Tank swap 003.JPG

    Cheap JCWhitney "carpet"(It's more like bonded together fuzz) is stapled to the wood.

    Wow Gordo that is an awesome custom rear deck. That is super nice work. Certainly something I haven't thought about, but worthy of entertaining in the future. I like the idea of having more room in the rear area. And really how often do we have a flat tire
    I have always wanted to keep my Opel as close to original, but who knows

    Two words Gordo, Dam Sweet. Well I see now, that I'm going to clean out my shop. Then put my Gt in and work on it on these nasty days. I have 2 items from Charlotte that need addressing.

    Long story, but we made it home. Again, (Thank you, John), for the caps.

    So once we get done, I can head to New Jersey (for real this time), swap cars and let you loose on my car. I don't have the New engine and 5 speed in yet, but I can drive the slow lane. Better yet, put it all on my trailer and caravan up there, drop it off, and let you play with some Dual Side Draft Webers, and finish off my Getrag (Gil knows what parts I need.) Hows that?
    Oh forgot to add the Cam, Roller rockers, stud girdle and poly locks. Parts acquired and stashed long ago, and Powdered Valve cover. (Roller rockers, stud girdle and poly locks), were purchased when Samdog made it, Gtjim (rip), reworked them, and sent them back. This was long before you got on the board. Anyway Greeat Craftsmanship. Yeah, I got and kept "Stuff". I knew someday I was going to retire and some "Young Wippersnapper", would show up and put them all together, (I could watch).

    Attached is what I am starting with. It came out very easy so I will replace the wood on top and recover with new vinyl. I will post my progress. Thanks for the shared posts.

    The pictures don’t show it well but the cutouts are not symmetrical and a white silicone adhesive was used to cover them with flashing before I got the car. All this was covered with a rear deck cover.
