Transmission swap

[Sander]

My 1979 K5 Blazer has a TH350/NP203 combo. The transmission needs overhaul. I have a TH700R4/NP208 combo with only 2000mls on it lying around. Would that be a straight swap out or do I need to relocate support brackets on the frame?

iirc, the th350 is shorter than the 700r4, so you might have to move the crossmember for the trans back some... definately not undoable

Driveshaft lengths will be different also.
