In Progress Floor Pan install....question. #266590 03/25/09 09:50 PM 03/25/09 09:50 PM

I have the car up on jack stands supported at 6 points and leveled the car out front to back and side to side by shimming the floor jacks. It's supported under the axle tubes, the front wheels are up on car ramps my Gramdpa and Dad made back in the 70s and there is mid support under the brackets that come off the rocker a couple inches. Anyway, I took my time removing the old floor as this is my first floor pan install. I used a spot weld cutter and various tools to remove the floor. I tried not to butcher it up. The new AMD pan seems to go in pretty easy but my issue is the floor pan lip on each side seems to sit too high. But when under the car, the pan seem to be sitting on the center brace, meeting at the front cowl lip, and sitting on the two small brackets coming off the rockers. It just seems as though it is sitting high when I compare it to where the spot weld cutter marks are on the rocker. So I am not sure if I am missing something as this is my first pan install. Is there a method to installing this to where it will drop in? Should I start in the center out?... or use something like sheet metal screws to pull it down? I also thought about using a hammer and dolly to massage the lip a little. It seems like it is 1/4 inch or so high in a couple spots. Others it seems fine. Even the holes in the new pan seem to line up with the holes in the brackets flush below it....I am a novice so any friendly advice would be much appreciated.

But the new pan seems to sit just below the indent. So I am not sure if there is some adjustment that I need to be making, if this is common, or what. The last pic is just of the floor pans sitting loosely in there (no clamps). I did put some clamps on it, but it still seems high in areas.

Sometimes repro pieces have extra material along the edges to allow you to custom fit it to your vehicle. I can't speak for the fit of AMD pieces, but there's no such thing as a perfect fit when working with repro sheet metal, so the hammer and dollies will come in handy. I suggest you buy and use some Cleco pins to hold the pans in place while your fitting them, too. If it feels wrong and doesn't look like it's fitting correctly, don't weld it yet.

Could be that the new pan is a tad deeper on the side????

So some tweeking will be required. If the pan sit flat on all the braces and cross members and be attached to the rockers properly, then I think you are good. 68 Road Runner (383/4speed, post car w/decor pkg) - Major Project 69 Road Runner w/472 Hemi & 4 speed. 70 Challenger R/T SE EF8 w/ V9J, U - A32 - Major Project 2023 Ford Mach 1

Where it stands now, it still could technically be installed, but I don't think it would be right. Everything seems to look the same, so I am having trouble pin pointing what is different. I will retry clamping everything and see if I can massage a better fitment out of it. Try to take some better pics if I can.

I took the pan back out and went around the rocker and tapped down a few high spots I found. Looking at the line I marked it seems fairly close and only high towards the back. I took the pan and massaged any high spots or possible inconsistancies in the lip. Put the pan back in and really tried to pay attention to how it matched up with that line on the rocker I drew. I pressed down in all areas to make sure I would sit flat. I think I may have found the issue. Previously I said it was sitting on the brackets but I think it may not have been flat on the brackets. I hadn't noticed but the brackets actually point upwards towards the center of the car. I guess they help sort of pre bend or put a slight amount of tension in the pan. I pressed down on the pan at the brackets and it sat more flushed but pulled up a little on the other side. So this weekend, I am going to go around and clamp in the lip where I want it. Hopefully this is take care of it. I'll have to do the whole perimeter to make sure. Keep you posted.

At times we would center it and get it close put a few screws in it beat the rest with hammer dolly few more screws then have someone stand or push with a hammer handle at an area while welding.
