The WS6 bar is 1.2" and the standard T/A, and Z28 bar is 1.125" For a 1.25" bar you would be looking at the aftermarket.
I checked and I don't have a spare WS6 bar. They are pretty rare. I will be going up to the shop where the camaro stuff is and I think I have a 1.125" bar there.
Hi Racer I already have the 1.125 bar in my 70 GTO.Had read that all T/A's had the 1.25 bar in.I guess I might go aftermarket or try and find a WS6 bar.Thank you all for the info.
64 Custom sport I believe is correct.Did some research and I guess it's true.All 70 -81 T/A's used the 1.250" bar.Thanks all for the help and I'll keep looking.
