How far does the front spleen have to go into the
the trans tailshaft on a 350 turbo chev? I'm put-
ting a rod together. Mine goes in about half the distance about 21/4" on level ground. Is this enough?

Thanks K Stok

as a general rule when fabricating a driveshaft the front yoke should go in till about 1" to 1.25" before touching the yoke flange....about an inch to an inch and a quarter play, in and out unless you have special circumstances

Really glad you posted this thread! Got my TH350 rebuilt and now putting into the 62 belair (where once was a C.I. Powerglide) New Yoke on the way (26 spline) but a couple of people have said that I "May" have to shorten the Propshaft, anyone have a definative answer? Cheers.

Oh and would Hydraulics be classed as a special circumstance?

Thanx again in advance!
