Ron Tredway is restoring his Owens-Corning '70 Camaro Trans-Am Camaro originally driven by Jerry Thompson.
He sent me these photos of the original double-adjustable Konis that were on the car. The shorter front shocks
are #8210-1067 and the rears are #8210-1068. All are dated 3-70. Thanks for sharing these with us, Ron!

Did they all have spherical ends? Or was this a modification?

I have asked Ron and he's unsure of the answer. He said he would check in with Jerry Thompson to see what he might remember.

These are GM-issued Koni shocks, available through the parts department and, in the case of Firebirds, available as a factory option from what I have been told.
These not only have a Koni part number on them but also a GM 7-digit part number. The front shocks were part # 80A 1914, 9791593 and the rear shocks for
multi-leaf applications were part # 80E 1953, 9792749. For some reason, Firebird used a different Koni part # on the rear multi-leaf shocks in '69, 80E 2025
rather than 80E 1953. Thanks go to Robert Lodewyk for sharing these from his personal collection.

Sorry for the late reply on an old thread.

If the Koni double adjustable seemed to be the one to use in Trans-Am back in the days, what about today ?
In your opinion what is the best front shock to use today (TA legal) ?

In looking around the race paddock, I'd say that most of the HTA guys still prefer a period Koni double adjustable shock.  People like http://performanceshock.com/ (PSI, at Sears Point) can do a wonderful job restoring/rebuilding them to proper race spec as well. 

Performance Shock can also build new double adjustables, that look and perform just like the originals as well.  They will not however have a period date code (if that matters). 

You might also consider looking into whether http://www.truechoicekoniracingservices.com/ can help you with some new Koni shocks. As was discussed previously in this thread, True Choice has been able to build new versions of their old double adjustable shocks and it's possible they are still offering this service.

As for what other shocks competitors might be using, I honestly don't recall. You will not be dissatisfied if you were to go the Koni route.
