The ones they sell for A-bodies are B-body length, IIRC. Clair used GM A-body QA1's (Chevelle, GTO etc) that have a shorter body and changed the upper mounting hardware with a kit from QA1.
But GMachineDartGT, do you think those are valved for 1.04 and above.
You guys remember 1.04 Tbars are a significant jump from 1.00" T-bars. Were' talking a little over 20% more wheel rate.
GMachineDartGT, I just got some 1.14" T-bars with not a lot of miles on them. What's out there that can handle that? Those 1.14's are 75% more rate than 1.00's. And almost THREE TIMES more rate than stock 340 T-bars.
