When I redid my 70 Coronet,
I used the only available outer wheelhouse (and taiwan quarter skin)
available at the time (circa 2004).
It was thinner guage than the original was by far...
But, I was able to get it on and it was a hell of an improvement
because so much of the outer wheel house was completely gone.

To it's only credit, It mated perfectly to the reproduction quarter
skin (again it was all that was available at the time)....


As I recall the only modification I had to do was the inner flange
where it mated to the rocker panel... the lower outer wheelhouse was
out to far at the lower rocker panel....

Basically you move up from the lower flange about 12-14 inches
then cut, flatten, then rebend the flange so that the lower portion
comes in almost flush with the rockerpanel...

The time consuming part was, once you bent the flange you had to put
the wheelhouse on the car (with vise-grips), the trunk drop, and then
the skin and refit it all until the qtr laid flush with the lower
rocker down flange...

There was an article about this in mopar muscle magazine around that
time-frame (2003-2004)...

The reproduction wheel house (at that time) also mated perfectly
with an NOS quarter panel but like I said it was thinner guage so
welding it was a little tricky...

Also, the factory rear wheel opening mouldings laid perfectly on the
repro skin...


I quess I assumed that since AMD made the 68-69 BBody Qtr, they made
it in conjuction with the outerwheelhouse...
I had no idea that their OEM style quarter did not mate well with
their outer wheelhouse...


While I cussed and screamed about how thin the metal was at the time,
Even the cheap Taiwan quarter skin/wheelhouse at least mated
together!

I'm shocked that AMD would spend the time and money tooling the
quarter and tooling and re-tooling the wheelhouse and they don't
mate....

You know this is 2011.... not 1971... 40 years later and for some
reason companies still can't build parts that fit... Go figure...
Why is it so hard? We have Cad/Cam, modern computers, modern tooling techniques
and 100 years of tooling quarter panels/ sheet metal practice...
but still no cigar...

My ignorance obviously...
