91 mustang swap question

[Dekster]

So my mustang chassis is bad (very serious rust) and I am thinking i should just find a new one to move everything over. Everything else is good/repairable or i have the replacement parts.

The engine/transmission is stock. What year(s) will i be able to move everything too without too much hassle, including a chassis that originally had an automatic transmission?

I have a 91 mustang 5.0

I know in 90 the radiator core support changed, I believe the wheel wells are larger up front on the later foxes. I'd say 90-93 to be safe? I mean if you're going to swap the whole car than any maf equiped 88+ would be fine, or -87 if you're up to the conversion?
