    Posted: Aug/11/2019 at 6:54pm
when I traveled to get my ‘rust free’ 70 AMX, I saw it had quarters put on it. What I didn’t realize until stripping the car is that they were put on pretty poorly. I’m hoping you can zoom in on the pic. 
  Just below the tape is a groove that was ground in the quarter. He actual seam is a couple of inches below the tape. The inner section next to the trunk pan was also replaced. 
  The shape of the wheel opening is off, and the bottom of the quarter isn’t flat. The rear panel under the bumper hasn’t been fit (the holes were filled with bondo). 
  So, at what point do I decide to get new panels and start over?

I’d redo that, no reason to put a decent paint job over that sort of repair.  The lowers rear patches are about $200 I think and it is a pretty straight forward job if you have a mig welder.  Andy

It looks like a panel that had collision damage and a rust repair.

And maybe a home made patch,  that didn't go nearly high enough.
I've got nothing against home made patch panels,  I do a lot myself.
But I've got a Mig, Tig, English wheel, plandishing hammer , beading tool, shrinker/stretcher, etc., 30 or so body hammers and dollies, and 45 years of using them.

 Maybe also welded,  probably with a mig,  but in too big a rush.

You can get serious warping, even with a mig,  if you don't use a sensible welding plan,  and pause ever few welds and let the panel cool. 

It'd probably be better with another panel welded on,   I'll bet behind that welding around the wheelwell edge there's a bird's nest of welding wire .

if you can get a good repair panel then I would replace as much as possible it save time on body work and make for a much longer lasting repair for no rust issues

Use the lower patch repair panels. They work and I've not scene a good use full quarter panel in about 10 years. LRDaum

I would must likely replace the lower area with the replacement panels available from the AMC vendors. This would allow you to clean up or remove any other imperfections or rust ( at the pinch welds). Taking a chance on possible bad, poor or incomplete prior welds would also be eliminated.

Is there just one manufacturer of patch panels, or does someone have better panels? I see that Kennedy and APD both have similar prices and descriptions, so I'm guessing they are selling the same panel.

I'm assuming that I want to avoid the 'economy grade' ebay patch panels.


Thanks for confirming my gut feel, do this stuff right.

The 3 main AMC vendors all sell the same panel- I believe that they share tooling costs up front and then sell the part at the same price. They do this with most, or all, of the reproduction parts. Avoid the Ebay and generic panels that some guy is hammering out on his picnic table.

Edit: you now have to modify your signature
