I have pinholes throughout the floor pans of my GS. Would it be easier to replace the entire pan with a 1 piece pan or weld in the two sections and leave the trans hump? The 1 piece pan already has the bucket seat brackets in place so that would help some. The 1 piece is made in the US andwill cost about $310 and the 2 piece is also made in the US and will cost about $230. While cost is a somewhat of a factor, easier installation and the best quality/finish is the most important thing. Thanks in advance.
I have the same problem with mine as well...just finished taking all interior and carpet out last night....I'm getting water in from the front cowling...and a few rotted spots up front... I'm thinking of which way 2 go also...full pan or partial..... I will be on the sidelines watching this post... I'm thinking of this http://cgi.ebay.com/ebaymotors/ws/e...ry=10076&item=4538454803&rd=1&ssPageName=WDVW but my welding/tac welding is limited.....
Hmmmmm I'd like to know a little bit more about the floor, but looks great from what I can tell. o No:
Replacing floors is a PITA if it only has a few pinholes consider buying the 2 piece floor and confine replacement to the bad area.Cut your floor to good metal then cut the new floor to fit.Weld the patch solid and finish top and bottom with filler to make repair invisible. Tim
I've done it both ways...the way Tim suggested more often. Once the small bad sections are removed and replaced with new metal, always coat the inside of the entire floor with something like POR-15 before the new sound insulation and carpet are installed.
I have done several floors also. If you have a lot of pin holes, rusted areas, I would go with new 1 piece floor pan. Cutting and patching several areas is a major time consumer and to me won't look good when looking at the bottom of the car. If you have a plasma cutter or can rent one, get it! I bought one and it makes cutting panels a breeze! I would also inspect your floor pan supports while you are at it. They have a tendency to rust from the inside out. They are about $80 each. One goes across/before the front seat and the second one goes just behind the front seat and serves as the anchor point for the front seat belts. Also, you will need to get a 3/16 hole puncher and panel flanger. I got mine from Harbor Freight and it works great. You use the hole punch to punch holes in the floor pan and then the surrounding metal floor. Use panel holders called Clecos, these are great. You can buy them from www.racerspartswholesale.com Now you can lay the new panel in position and use the clecos to hold the panel in place. Now, time to weld the new panel in position. Once you pass by a pin, you can go back and weld it shut. Then get a good grinder and grind the welds smooth. I use polyurethane roofing and flasher sealer from Home Depot to seal the seams (comes in a caulking tube) I use a plastic body filler squeege to make a nice smooth seam. Up to you to figure what your time and patience is worth when tackling this project. :TU:
