how to change 85-04 mustang t5 transmission input shaft (project mustang) 

Use some marine grease to hold in the needle bearings and the round one. Helps a lot

The v6 did. He states it’s out of his 2002 v6

Yes the v6 mustangs used the t5 and the gas used the tr3650 I believe

@@fixitauto1616 T5 only came in the 94/95 SN cars, 96-98 used the T45 and 99-01 cars, and I think they switched late 01 for the TR3650 until 04 and of course the 03/04 Cobra got the T56.

​@Mike-Honcho- in V8 Cars you are correct, V6 cars had the T5 from 1994-2004, only reason I know is because I pulled a T5 out of a 98 V6, reason ford did this was to keep cost of V6 down to nothing, it shared alot of design with the old 5.0 block, and the new 4.6 V8s got the t45 because it was entirely a new bell housing design for it amongst other reasons such as torque and power output

​@@Mike-Honcho-you clearly don't work on these cars at all
