We are replicating the original Gr4 sway bar set-up FOR MY RACECAR and are looking for the bar-clamps marked in the attached picture.
I thought they would be easy to find but no luck so far. Anybody know where to find them?? Bars are 22 mm (7/8") diameter both front and rear
I'm not looking for opinion, just help to find the particular parts

Those clamps were likely made in a race shop- not a difficult chore. Contact Les Gray in CA <tipo874A@msn.com, or Guy Trigaux in N Carolina <GTD2860@gmail.com> They both own real GR-4/GT-4 racers and may have spares. Good luck, Kristian.
I had mine made in a machine shop, as suggested by Bosswrench, but I've also seen racers mill the sides of the sway bar and bolt the link directly to the bar.
Also try www.pegasusautoracing.com in Wisconsin, as that swaybar clamp looks like the ones used on older formula cars, and Pegasus sells such bits.
You MIGHT need that adaptability on a full clapped out race car, maybe, but on a street car use the sphere balls so the bar(s) doesn't bind in the mount and as high a strength bolt as you can find.
The rod ends go with the adjustable link and that is for adjusting to varying tracks that you are running the car flat out on.
Those rod ends may not have the desired life span that you would like unless you have your own pit crew to go through the car for two or three days before you want to take it for a ride "up the cannon".

Yes you're right - It's NOT a street car :-).

Hum. I think that I remember seeing those clamps on GT40's? Their bars are mounted high over the exhausts so they are easily accessible without jacking the cars.
I'll see if I can find the pictures?
Doug,
Let me refresh your memory. Scroll down a bit to see an original GP4 setup from candy2862. May not be in the parts catalog but it was on a car.
Thanks for all the input.
Just to clarify, we have had the FACTORY gr4 sway bars (similar to the ones from #2862) produced/copied from an original set of bars, and only need the clamps to finish the set-up. We will have the clamps fabricated if we cannot find a current source for them.
Thanks
push,
Have you posted this on the deTomaso bulletin board? It tends to have more posts from the European community.

I remember that post Husker but I know that I saw those clamps available somewhere around 5 years ago. I just can't remember where.
I'm very sure that the same type was used on the GT40's when Ford raced them. It's PROBABLY a common design of the era?
I'm not arguing what did and did not come from the factory on the Gp 4's. The very nature of race cars tends to show that they aren't all completely alike.
"Improvements" are made along the lines.
I'd guess that it's more important to have the "classification judges" satisfied as to what is acceptable or not at this point.
I have pictures of the Gp4 that Stauffer had around 1992 somewhere but they are on slides.
He was at Watkins Glenn with it and I was more fascinated by the stainless headers in the car, the big wheels, the flairs and my 4 year old kept climbing on the car so my attention was divided just a little.
To expect the clamps to actually have been marketed is a little unfair. So many of the parts on the GT cars were hand fabricated to begin with.
Doug, George Stauffer will be the main speaker at the Phoenix Fun Rally in late April. Bring your kid and get an "Updated" photo!

Doug,
Your diagram is mislabeled. That's the Group 3 racing parts diagram, not the GT-4.
You Are wrong too. The diagram is the GTS option List.
@gts posted:You Are wrong too. The diagram is the GTS option List.
It isn't an argument to defend my comment that the diagram is a Group 4 parts list. What ever it is, it is. I just find it strange that a full roll cage would be offered for a street car rather then just a roll bar?
Considering that I suppose the philosophy of Detomaso was, "cash talks, nobody walks" explains a lot.
I would at least concede that the diagram is incomplete as compared to what we have seen on Group 4 cars, presuming that all of them were identical, which I kind of doubt anyway? That the Group 4 cars that I have seen, limited as that is, had rear braces to the roll bar to the top of the rear wheel tubs, or the rear deck lid tie downs that don't show in the diagram either.
I wouldn't accept the title of GTS diagram just because there are GTS decals offered in the list as proof.
In any case, Push is on his own to fabricate those clamps. I can't find any premade anywhere right now. Perhaps one of current the GT40 "continuation" manufacturers have made some available?
There are likely variants of the design across the 14 original group 4 cars, some photos I have show the bracket welded to the bar. Les Gray has what is probably the most unmolested Group 4 car, maybe he can shed some light.
Doug is heading in the right direction for a similar GT40 part, although bars are not notched for a through bolt.
Does the Pantera version bolt through? I thought that the entire point of the clamp was that it slid to change the leverage and the length of the link adjustable so that it made the bar much more tuneable?
All the real Gr4 factory cars that I have seen have the same sway bar set-up, the rear like in the first picture I posted (from Guy Trigauxs #2860). That includes Les Grays car and Patricks Hals Candy car # 2862.
The bars we had made were produced by a German suspension company H&R, and are true copies of a factory set of Gr4 bars that we borrowed.
The rear bar is 22 mm and 5 way adjustable with notches in the bars that the clamps slides over. The front bar is also different from the street bars and are 2 way adjustable (see picture).
The bars rotate in solid aluminum mounts on the chassis, the front mount raised some 2". The rear bar mounts are moved outward as shown in the pic in first post.
Still looking for correct clamps ...
This is as close as I have found so far... but it's 3/4"
