I use to buy the longer A motor clutch rod, not sure if it was for E bodies only or for all three body styles or not, to use in my 1970 Baracuda with a 1968 hemi motor with the stock bell housing and 170 tooth flywheel. The original rod, that car was a 383 4 speed car originally, was to short to stick through the clucth fork, the A motor rods was long enough to go all the way through it which made it stay in the fork better when speed shifting the car when I raced it later in NHRA stock class, I remember fighting those stock retaining clips to stay on until I figure out which way the opening needed to be facing on the Z bar to hold on
I'm sure the rod you have is exactly like the stock A motor rod I use to buy and use on all my stick shift cars
