Opinions needed. Combine two to make one or Sell one use cash?

Here is my problem...

I have a 1970 Suburban that needs help
I have a 1972 parts suburban for the glass and other misc suburban specific parts.

Where I am confused is the source for the other parts to make it go and give it 5 lugs.

Thats where the 1972 Blue chevy truck I currently have comes into play. It's Decent shape but nothing special, alot of rust and just that its an old farm truck I wont use. Runs and Drives with a 350/350. power steering and brakes.

So here is my question:

Would you part out the 1972 to provide engine, trans, radiator, wiring, and 5 lug parts for the 1970 Suburban, or sell and use the money for the parts?

But Hold on a minute, there is more.... You have access to each of the parts you need but they are of unknown condition. Must be rebuilt or reconditoned.:
1* 1976 350/350 combo
2* 5 lug rear (no brake parts),
3* 5 lug front suspension *would need to purchase at a cost of 150*
4* wiring from other parts trucks

It boils down to this, would you part out a decent running 1972 to build a decent runing 1970 Suburban? If you had the parts but each part required rebuild. I guess that depends on what the 72 is worth as a complete truck?

Would I come out better by parting it or selling it and the extra parts when I'm done?
