This quarter-panel has been patched before and is now rusting through inother areas. Patching it again would be a total waste of money since itwill eventually rust through somewhere else. It's vital to remove thepanel, and find out what's going on behind it.
Cancer, there are not many words that ring with pain and death as muchas this one. Whatever treatments are employed, they must have one endresult: all cancer must be removed, or it will eventually come back tohurt you again. A band-aid won't fix this.
The same is true for rust.There is no place for band-aids or patches in any real restoration. Rustmust go. Period.
A new panel from Year One...
A new panel from Year One is placed over the original to show you whatis traditionally removed from the car.
There isn't anyone who would argue with this, but youwill get disagreements about the best course of treatment. John Balow ofMuscle car Restorations has learned in his sixteen years of experiencedoing first class restorations to be absolutely merciless in dealingwith rust damage. The reality is rust works its evil deep in the nooks,crannies, and hidden crevices of your car. Even if you properly repairthe damaged part of a panel, you really don't know what other damage isoccurring behind seemingly solid areas. There is no form of CAT scan tosee what's lurking behind sheetmetal. The only true long-term solutionis major exploratory surgery--completely remove the panel and treat theentire area.
John and his talented craftsmen have raised the standardfor panel replacement. They are producing results that are practicallyindistinguishable from an original factory panel.

Muscle Car Restorations insists on preserving the original compoundcorner at the top of the quarter-panel, the taillight extension area,the marker light position, and door jamb seams. That way, the usualtell-tail signs of quarter replacement are eliminated, and, moreimportantly, the original factory fit is completely maintained. Thepositions of the cuts are clearly marked out in advance. The cut linesare lower on the original panel than where the finished seam will be.

With the old quarter removed, you can see there is a lot of gunk thathas accumulated in the bottom seam on either side of the wheel opening.In fact, in the front corner of the wheel opening there is a good dealof old sandblasting sand from the previous patch job. All of this debristraps moisture, even right out of the air, not to mention each time thecar is washed. If this isn't cleaned out, rust will come back again andruin the restoration.
Preserving the original marker...
Preserving the original marker light opening not only maintains theoriginal factory fit and location of the marker light, but if this cargets the rear stripe, it will fit perfectly, as well. As good as thereproduction panels from Year One are, the marker light openings are notalways identical with the originals.

...The tools for removing thefactory spot welds are a Century 1/8-inch double-ended drill bit and a3/8-inch Blair plug cutter. The bit works for marking the center of thespot weld and providing a guide for the point of the plug cutter.
