2wd 1/2 ton to 3/4 conversion question

[bulky]

Looking for some input on a project I have in mind. I have a nice 2 wheel drive, 1/2 ton 1985 long bed pickup. Recently I got a line on a 2 wheel drive 1983 3/4 ton suburban with a 454 in it for cheap money (Body rotted but drivetrain & frame good). Engine /tranny swap is not a problem. My question is are any of the frame points different? Can I remove all suspension, upper / lower control arms, front & rear springs & shocks and just move over to the 1/2 ton frame?

I had just planned on doing the motor / trans swap but figure if I can upgrade the whole unit......why not.

Thanks

I'm not so sure you'll be able to get much of it to fit. I know that the burb frame is taller than a pickup frame for sure, and that the rear spring hangers may be different too..

No point in the suspension swap IMO. Maybe the rear springs but they probably aren't the same length [even 1/2tons had 2 different sizes] and 1/2ton HD 8 pack leafs are easy enough to get [both my 1/2's had em] I would just put some helper air bags back there myself.

Motor and th400 are worth swapping though

Thanks for the info...
