View Full Version : Installing Trunk Pan

I've finally gotten to the point of installing my trunk pan. We started by rthe moving the body from the frame to get the pan in place. We set the body back down, got the forward flange inserted into the seam that runs horizontal across the back seat. Everything seems to fit pretty well but we can't seem to get the body back onto the body mounts. Everything seem all squared up but we can't get the body back far enough to line up with the body mounts. We are about an from being perfect. We checked everywhere and can't find anything that's hanging it up. The first couple photos are just a general view of the rear.

The last thing I'm baffled with is the gap between the trunk pan and rear quarter panel. Is there a filler panel or am I missing something. The third photo is from the rear looking forward.

Thanks for any suggestions!!!

i recognized the taillight opening as 68 :banana:
you are missing the drop-off panel in pic#3
they go between the 1/4panel & trunk floor pan

Awesome. Went shopping and bought them this morning.

Now, back to my other issue. The replacement trunk pan is one piece and getting it to fit is something of chore to say the least. Is it better to get the body pinned down and secure using the new body mounts and then slide the trunk in? We tried that but we couldn't quite get the pan to slide into the seam that runs across th back firewall. Nothing appears to hang I think up. I wonder if makes sense to cut the pan, fit the pieces then weld back together.

Any other experiences out there. I need heeeeeeeeeelp :):)

Thanks in advance

Make sure your body will fit back on the frame with new mounts
because sometimes they flex around.
How are you supporting the frame and body.??
More pics.
Before you weld in any new metal....2 coats of EPOXY primer.

Thanks mestorod. The frame is on a rolling cat that is level front to back, side to side. Today I pulled the pan out just to get the body back on the frame. I've secured the two front body mounts and the one located just behind the passenger seat. I found a new issue. See first photo. The previous owner had separated body from frame by snapping the bolt off inside the floor pan. No I mean not sure what to do. Has anyone tried a different method of securing body to frame other than stock locations. Maybe some other bracketry welded to the underside of the floor pan?? Second photo.

As always, thanks for your input.

I should noted that I have already sandblasted the frame with a coat of primer. I've also boxed in the frame and welded in new steel sections for strength. Once I have the trunk pan in place and new wheel tubs in place the body goes out for soda blasting and epoxy primer already for the cool stuff.

is that a caged nut??:mad:
you should repair it while you have access
i think you cut it out and replace the nut and also repair the cage

X2 I opened it up and fixed it. Then welded and grinded it. So it looked factory. I snapped off one in the same place doing mine. There is a square Fred Flintsone looking nut in there.

Thanks for the feedback. It's was I figured. Right now I need to get the trunk pan and new wheel tubs in place. Once that's done then I'll repair that caged nut. Crap:grumpy:

Chevey,

I did get the trunk pan installed in one piece. Since I had to replace both rear quarters, I removed enough of the quarter panel to slide the trunk pan from the side and rear. Since then I've spot welded the new wheel tubs together and spot welded in place. Dimensionally everything lines up perfectly side to side, front to rear. I've already temporarily fitted the new quarter panels and now I will make my final cuts before I have to but weld a mile of joint haha. I did learn the best way, or at least I think it's the best way, is to use a pneumatic flange tool that creates a beveled edge for both edges that creates a valley between the edges so when I stitch weld the joint it provides more weld surface so when I grind down the weld I don't run the risk of the joint cracking. If you have a better idea I'm all ears :D

Mestorod70,

I eventually had to cut the quarter due to rust and found getting that quarter section out made it a whole lot easier putting the trunk pan in.

Below are a couple video's using a manual & pneumatic flange tool. I have a pneumatic one. I haven't started the work yet but after seeing the video it makes perfect sense. I do have to admit that I'm in no way a professional body man but... it does make sense. Perhaps if there are any body guys out there hopefully they could chime with their experience. The second video shows using the pneumatic flange tool.

Your new quarter should be installed in one piece.
