Hi, thanks for the info. The T-50 would be nice, but I think it's a top
loader and may be too far back in the console (like the T-5 and T-56). I
was thinking if I could use a side loader like the MY6 there would be a
chance to bolt it in as a direct swap. The one I was looking at was named
the NP440 O/D 4 SPEED from a mid 80's Chevy truck. It was sitting in a 57
truck behind a 283 and all the shift linkage swapped right over (I think
they had pulled out a Saginaw 4 spd). The length and output shaft were ( I
am told) the same as a TH350. If they are prone to gear whine and failure
I may just stick with what's in there. Thanks again.
