    Motor mount shim

    Couldn't find any info on this in any of the forms. under my motor mount on the driver side was a 1/8 inch thick shim. Has anyone ever seen this before ? I understand the engine is tilted to give clearance for the air filter box and this is accomplished with the motor mount brackets.

    You should have that shim on both sides (at least that's how it's been on both of my GTs). I think they were between the crossmember and body though...

    The crossmember shims are some sort of phenolic/plastic material. They have two holes per shim, so the metal shim in the pic is definitely not the same piece.

    Looks like someone may have used an alignment shim to help prop up a sagging engine mount.

    Guys, this is a factory shim for between the engine frame and the body frame. If you run a factory sway bar, these are removed and the mounts for the sway bar are used instead. There will be two, one on each side on the inner most bolt area


    Now I've seen them mounted other places because people didn't know where they came from.

    Crossmember to body frame phenolic spacers go here on both sides, each have two holes for the bolts that secure the crossmember

    Thanks for the help.

    I do not have the shim for the sides or the phenolic shims
    Their is a guy close to me that has stripped a lot of cars down for parts.
    Hopefully he has the shims for both the side and bottom.

    if not Could you give me the thickness of both so I can make something ?

    Again thank you for taking the time to help

    I hope you realize, this is about two different cross members.

    Engine cross member requires one shim on both sides, you are showing it in your picture. Those shims should be installed as per Keith's instruction few posts ago.

    Front suspension cross member requires phenolic inserts and they are available from OGTS Fiber Spacer - Original Front - Suspension - Opel GT - Store | Opel GT Source

    Yes this makes sense. Not pulling the suspension this year and I checked and the fiber spacer is their on both sides. Ill duplicate the spacer to go between the eng cross member. Hopefull the cars coming back painted soon so I can start putting it together.
