What is the best way to replace a floor that is completely rusted on a 1992 Geo Tracker?

I think you've just about had your money's worth out of that little feller. Replace all that floor pan and you're going to find the crossmembers are rotted, so it will fail inspection anyway. And just how many miles do you expect to squeeze out of that little 3 cylinder engine after you've done it all?

Well,it's a FOUR cylinder,and thefloor can be replaced,i replaced mine from yhe firewall to the back door,and the rockerpanels,don't give up.Of course I did all the work myself,if I had to pay someone I would have got another one and kept T2 for parts.
