I have managed a couple of photos of the rear quarter replacement on the army sedan.
The car was modified in the 70's and copped some huge flares which pumped out not only the outer guard, but about 4 inches up into the inner guard as well.
Here is the replacement inner guard, note that it has some rust as well. This will be cut out and repaired before installation. Nobody would let me chop up a good car to get some really good inner guards. Pity because the army sedan had no rust in the rear quarters at all.
Here is the NOS rear quarter in place - it all fits quite nicely.
