I have a '83 camaro z28 with a rusty floor and the panel right in front of the floor. Not the firewall. How should I go about replacing these parts. I have a '87 with decent floor parts very little rust in the floor area. should I just cut them out and weld them in. How difficult is it to put new floor pans in like the ones from Classic Industries.

has anyone done this before. any help would be nice.

Did it on my 76 T/A resto replaced most of the floor ..If the floor isn't to bad Just replaced the parts that are bad..And if you don't need to replace much of it just make your own patch..Take your time and make templates...Good luck
