Rear transmission support
Hey everyone. Apparently I have an early addition Turbo 400 in my 73 and when I ordered the new rear support bushing it had 3 3/4” hole spacing to attach to the tail shaft, and my old one is 4 1/4”. Anyone know a part number or where to get the correct mount? Appears that most places only have the 3 3/4”, including The main Corvette parts places online.
i ran into this problem when trying to fix the leak at my shift rod. No seal, just an O ring.
thanks for your help.

Some TH350 had the long tailshaft housing & tailshaft. It depended on which GM model it was going in.
Perhaps the TH400 has this same issue and has the different mount. IDK
You should Google: Images of TH350 & TH400 pans. Then verify you actually have the 400. The pans shape give away what trans it is.
Who knows what trans you have after 47yrs?
