Default 400 Pontiac & 350 trans in '71 Chevelle

Hello everyone. I am thinking of doing this swap and have some questions. After reading a few threads on this forum and a couple elsewhere, I'm still unclear on some details of this swap.

Here is what I know I need so far.

frame mounts from a GTO/LeMans/Tempest
accessory brackets and pulleys
extend the fuel line that runs to the fuel pump
move the transmission cross member back for the Pontiac trans
run a new cable for the starter from the battery

Now for the questions.
Are the frame mounts the same for all size V8's?

If I use the Pontiac trans, is there any other mods to the cross member other than moving it back? I've seen the adapter to bolt my TH350 to the Pontiac motor.

Can I hook up my shifter linkage to the Pontiac trans?

Will I be able to use my stock drive shaft?

Will I need to get a new kick down cable for the Pontiac 350 trans? (I'm not sure if Pontiac called their 350 trans a TH350)

Will I need to get a different speedo cable?

Can I use my Chevy radiator, or will I have to use one from a Pontiac A-body?

Will it be easier to run manifolds instead of headers?

Will headers for the Pontiac motor fit on the Chevelle?(seems like a dumb ?, )

I know I'm forgetting things. I'm about to go cross eyed from searching this forum, reading, and typing. If you guys know something I left out, please post up. I would appreciate any and all help. Thanks in advance.
