1966 F100 Short Bed Styleside Metal/Body/Paint Work


I initially was just going to cut a hole and have the lid pop through, but that looked out of place/unfinished, and the metal at the front edge was pretty stretched and loose, so I made a recessed circle on the Pullmax and welded it in which shrunk the loose metal and it looks way better.

To make the recess I used a set of dies I already had that were meant to roll the edge of a panel. I took the backstop off and made a shorter flat piece to bolt in place of it, and set up the circle cutting clamps in the throat to make a perfect circle.




To roll an inner flange I tacked an old bearing race on the back and used a mallet to fold the flange in.

Welded together.




Difference in angle of the lower flange.



Spotwelds drilled to remove the '65 radiator brackets.

New lower flanges.



The donor inner fenders were better but not perfect so I had a few areas to straighten out.



I slightly rounded off the sharp corners on all of the edges.

On the back of the mounting flanges, I ground the outer edges at about a 15* angle to bevel the edges, once it's painted the edges won't dig into the firewall and chip the paint underneath.

This area was dented and I couldn't really tell what the original shape would've been, and after knocking the dent out the area was floppy/loose. The rest of the inner fenders have sharp, straight bends with flat areas in between and this area was rounded so it looked out of place. I made marks with a straight edge and hammered in creases with a chisel and hammer over a sandbag, then used the shrinking disk to bring the rounded areas down until they were flat.


After-


All of the original wavy edges were flattened, and I trimmed back the areas around the new crossmember to make more room for getting in there with tools to align it, and room for the power steering reservoir hoses.

Extra holes welded up.


The overall shape was way off after getting the buckled spots worked down flat.


I used a come a long and vise plus heat, hammers, and a 24" adjustable wrench to get it back in shape.



Linear stretching a spot I over-shrunk.

Decided to use an aftermarket filler panel, the factory one I had was rotted, so I got the overall shape pretty much matched up with the new panel.

I double checked the rad support/filler panel fit with the original filler panel to determine which part was shaped wrong; neither fit correctly so the rad support isn't shaped correctly.



The rad support had metric threads so I drilled them to the next standard size up and retapped the threads.

The bumper normally mounts directly to the frame with no ability to adjust it, but we asked No Limit to make shorter frame stubs with bolt on bumper brackets so the bumper could be moved around easier. The holes they drilled didn't offer any adjustment, so I cut the whole rear edge off to make room for moving the bumper back farther, welded up what was left of the holes, and drilled/slotted new ones once I had the bumper where I wanted it.


Filler panel mount brackets removed from the original panel, blasted, and straightened to fit the fenders and rad support better.




To fit the bumper closer to the body, I split the filler panel down the middle and initially overlapped it to do a test fit to see how far in I wanted to bring the bumper in, and settled on taking out 1".





I cut and bent 1/8" strips 90* and welded them to the bumper to hold bottom of the filler panel at the correct height. After the bumpers are plated I'll brush on Plasti-Dip to keep this from rattling.

Test fit on the truck.




Both corners of the bumper need to be trimmed to clear the body better, but now that the bumper and filler panel are in their final places I can start remaking the flanges and edges of the filler panel to mount correctly and fill in the gap around the bottom corners of the grill. I expect the bumper to slightly move around when the chrome shop does the final straightening, so I'll wait to get the filler panel fitting any better until after the bumper is back. I'll use the finished bumper as a guide for skimming the top of the filler panel to make it perfectly level with the bumper.
Regards,
Chris and Cheryl;

I used a reverse gear from an old transmission to linear stretch the top and bottom flanges until the curve was gone and the outer face of the bumper was flat.



There were weird bumps stamped into the top flange of the bumper above the license plate mount area, I hammered those down then used a sand bag and mallet to bump the surrounding low spots up.


Once the overall shape was roughed in I started picking/filing to prep it for chrome.



The peaks of the stamping around the tag mount weren't consistent so I used a rounded over punch from the backside to tighten up the radii where needed, then filed it smooth and blended the transistions.



Clamped in place for the first test fit. It still needs the ends reshaped to match the width and shape of the bed, and the brackets need to be modified for it to bolt up.
