Replacing the Floor Pans

[joeboy]

My front floor pans are rusty and gotta come out... I got the new pans from Yearone and would like to put them in over the next 2-3 weeks. I am looking for advice or hints on the best way to cut the old ones out, and get the new ones trimmed up, and welded in. I have a sawzall, a pneumatic cutoff wheel, and a small welder... HELP!

i need to do this too, i found this on moparmuscle.com. it looks like they overlaped the pans and welded both top and bottom. i dont know if other people just butt them up to each other i guess it wouldnt matter. good luck with your floors. i think the hardest part will be drilling out all the spot welds to the frame. i hope this helps a bit.

Butt weld them. Overlapping will create an area for rust to start.

Removal is easy with an air chisel.

I have complete pans available for less than the year one parts.

If you overlap them use some seam sealer and a good rust inhibitor.

Or a good non-burn metal bond from Fuzor, 3M, etc. A drill and a spot weld cutter will soon become your friend, too..

While you are at it: No one seems to see that the floor pan has to be pushed down onto the lateral and long unibody subframe, which are open at the top, relying on the thin floor for strength, at the top.
If you weld 16 gauge on top of them, the pans fit perfect, and you have more strenght than before. Almost like a real frame.

Thanks for all the help... I am gonna look for a spot weld cutter, and maybe borrow a pneumatic air chisel, so I can start the madness.

Good info here. I might add one thing. If you're using a plasma cutter to remove the old pans, make sure you know where your fuel line is. DAMHIK!!

Harbor freight= spot cutter, $5 and it lasts. And their grinder, with cut-off blades- lasts. Hand chisel works after that.
Just go underneath, and drill holes up at all important areas, then draw lines. Then cut. Support with stands, level, before you start.
