I rechecked the search and it was showing for a 3" diameter piece but you are right.
That place was high on all their stuff!
So a 1 1/2" diameter is large enough? Is that the same for the pan hard rod and stuff?
I'd crawl under the car and measure but it's to danged cold and there's snow on it right now.

I have several feet of 1" delrin rod. I use it to make spring guides and poppet valves for air guns.
1.5” should do the upper and lower bushings on both GT and Manta.

Do not use Delrin on the rear suspension, all the joints articulate in multiple planes. Not only will Delrin bind up, it will eventually crack and fail.

So you recommend staying with the poly ones OGTS sells for the rear suspension?
Its not gonna be a race car or anything.

My preference on the trailing arms for a street car is poly at the forward body mounts, heim joint at the spring buckets.

For the panhard bar I prefer poly at the axle mount, heim joint at the chassis mount.

It handles better than all rubber or all poly, but isolated better than all heim joints (NVH).

It also rides better than all poly. All poly tends to bind up on rough roads.

Thank you. Good info!

Keith's Restoration Handbook arrived today.
Very nice!
I got the Magazine Edition but I'll probably pony up for a Hard Back 2nd Edition.
The last Hard Back book I bought cost $150 so this one is cheap by my standards.
Last one I bought was about the USS Cyclops.

I'll measure the OD of the largest bushing in a little while.

Thank you.
Largest OD is at the flange. All measure @ 1.433"
Smallest ID is .625"
All are 1.315 thick.
8*1.315=10.52"

With room for cutoffs you would need a full foot to make all 8 bushings.

I saw at OGTS that the bore would be .745 for my 73.
A few more details and my Evil plans will come to fruition!

Here's what I have so far. ? is unknown dimensions.

Ordered the inside steel parts from OGTS since Sad Santa is sad.
:LOL:
Also grabbed some key blanks while I was at it. I can copy my key since I have a Key cutter. Got that YEARS ago when a Holiday Inn I worked at bought a new one.

There are two size bushings
My dimensions don't match yours.

I don't know which size bushing you are showing measurements for.

Would the 1.315 over all length match?
And the 1.435 match?
Bore for the metal part is based on OGTS metal part that goes in there for a 73 GT.

Hmm.
May just buy a set then give them away when I make my own if I can't get all the info to machine them.
OGTS will be calling me about the order so will go a head and do that.

I might have the earlier set.
I had 3 GTs when these were purchased.

I appreciate all your help.
It's probably better to just order the parts then duplicate them to be safe.
Not trying to take anything away from OGTS!
It's just that I'd like to make my own since I can. A little more personnel that way.
Anyone can buy and bolt on parts.
Same reason I want to use a FWD Engine adapted to the RWD set up.
Anyone can do a standard RWD 3.4 V6 install with minimal work.

No worries.
I thought about making my own a long time ago. I decided, after a debate with myself, Delrin was a little too solid for my liking.

All the stuff like this I replace on the 2000 Cadillac Escalade I stay with the stock stuff.
Wife drives it more then I do so want to keep her happy! (Happy Wife, Happy Life!)
The GT is MY Toy! And I do like that road feel.
First bushings I ever made were on a 75 Pontiac Trans Am back in 1979.
I didn't have a lathe back then. Made them with a drill press!
And if you happen to have the 2000 Escalade?
Pray the fuel pump don't go out! That thing is made of unobtanium!

So I'm ordering the front control arm bushing set from OGTS to make my own with delrin.
Once I have the measurements I need I will be giving the OTGS set away. You pay only shipping.
I have offered them to Mike, V6Opel, first. If he refuses them? Then the 1st one to post gets them.
I hope you'd claim them for personal use and not a resale thing.
I also plan to make several copies of the Delrin F versions.
Contact me by PM if interested. This is just a hobby so not gonna do a mass production.

I went with 1 3/4 inch Delrin F as I do have a few projects that can use that diameter.
Ordered 2 feet to start.

If you don't mind, where did you get it?
