ok i have a 79 mustang and the floor pans are rusted. its worse on the pass side but its not all the way up, it is floor board where the back seat riders feet go. its rusted all the way through in a couple of spots, can it be patch or would it be best to replace the whole thing. im trying to do it as cheap as possible cause i have other things that i need to buy

Its best to cut them out and weld in a new floor pan. You can patch if you want, with whatever type of stuff you want, but if its that bad the rust is still gonna spread until your whole floorpan HAS to be replaced.

is there anywhere i can get one without having to spend 100 dollars for each side?

not really i thought they were 80 or so , then protect the weld with some por 15 rust inhibitor ,good stuff

i have the same question on my driver an pass enger side there is one soft spot of rust on each about 1 1/2 2 inches big around bot really bad but i mean id like to fix the problem before it gets worse. So what would you recommebd i do? cause i mean theres only 2 total spots needing fixed of about 2 inches in diametere?

Best way to stop rust is to remove all the rust with maybe a wire wheel or something, then treat the area with some rust inhibitor. If the area is weak you can reinforce it with a welded plate or the best thing to do is just replace the floor pan, or cut the area out and weld in another piece of metal. Naval jelly works wonders to remove rust as well.</P>
