67-72 question engine trans/

[wcedgar]

Hey!
I need a good answer for this:
I have a 1970 Chevy 1/2 ton long bed pickup. Some knucklehead put a 350 Buick Engine & Trans in it when the motor went.

I have a 1984 Chevy 305 V8 and 350TH Trans I want to put in it.

This truck had a Powerglide steering column in it.

Here are my questions:

1.Do I need to change the steering column for the 350TH Trans or will the Powerglide column work?

2.Other than the motor mounts, do I need brackets that they sit on?

3.Do I have to use the 67-72 Transmission cross member? (transmission mount)

4.I think the 84 used the long tailshaft so can I use it and move the cross member back or do I have to use one with the short 6" tailshaft OR can I interchange tailshafts and put a 6" on the 350TH Trans the 9" came off of?

Thanks!
WC Edgar
