Trans tailshaft length
 

A friend is interested in the TH350 trans, when I put the 700R4 in it, in my stock unmolested 1972 C10 with 350 engine and 3:73 rear gears if that makes a difference. He asked if the trans had a 6 or 9 inch tail shaft and I have no idea which one it could be. Does anyone know which it would be for my truck or could it be either?

I think you are going to have to just measure it yourself.
Too many varibles of what could have been put in your truck over the years.

my 72 with the same setup, longbed, TH350, 373 rear gears,etc..., has the 6" tail. when i was searching around for a replacement at local parts yards and swap meets, i only saw the TH350, 6" shafts from the 71-72 trucks. the 9" was common also but the ones i found were from vans mostly

Both my 72 LWB C/10's were born with 350/350THM transmissions, both have 6" tail housings...
