Newer fuel tank in a 72?

[72LoBurb]

Hey guys/gals, has anyone transplanted a fuel tank from a newer 'burb ('90) into a 67-72?
I've already sacrificed my '90 'burb and plan to transplant the drivetrain (tbi 350/700) into my '72, but I'm on a budget, hence wanting to try fitting the '90's tank. I want to keep the injection and plan on going with the Painless harness and '90 computer.
I would go and start measuring everything up...but -15 Celcius is less than pleasant to work on a hobby/obsession vehicle, after working in the cold for 8 hrs a day.
Any help would be greatly appreciated.
