Need a little help w/80's k20

[Bus Ted Knuckle]

Hey guys, I spend most of my time over at the 67-72 board, but I need yoru expertness (is that a word?) with my latest project.

I have a k-20 that has been pieced together.
It currently has (I think) an 84 auto trans cab on a 80ish k20 frame that has a 350 granny 4 speed combo. I have no idea what t-case or axles at this point. It is basically just all set together, the engine+ tranny controls etc, are not hooked up. I got it in this condition. The guy got frustrated and gave up on it because of difficulty in getting this low hump (?) cab to work on this standard trans. It is missing some stuff here and there, but I have a pretty good 76 c-10 parts truck I can rob off of.

Questions:

1. Is there really any difference between an auto cab floor and a standard cab floor?

2. I have a cab on my 76 that is a floor shift model and the trans hump looks totally different. Will it fit and work on my K-20 frame?

3. If the cab fits, can I use the pedal assembly etc. from the 76 (the 76 is a 250-6cyl)

4. Will I have any trouble switching sheet metal between the two trucks? It all appears to be pretty much a bolt on deal, but there is a lot I can't see under all that

5. What parts will not be interchageable between the two trucks?

6. What am I not considering having to do when I start swapping parts from my doner 76 c-10, and this early 80's k-20?

I know, I ask too much

The good part:

both of these trucks were FREE, so I can afford to put a little $ into the project.


I really want to turn this truck into my main trailer hauler to free up my 69 to be slammed and tricked out...

THANKS!!!!
