Jeff,

Let me offer a couple of ideas. If you want to create an arc to use as a 
guide, maybe even as a stiffener on the backside of the finder lips you 
could use EMT electrical tubing. Use a bender to form the EMT. Biggest 
problem I see here is that the EMT would reduce clearance on the inside 
of the panel.

This is what we've done in the rear of the E/P 510. We had the add-on BRE 
(Bubble) style flares which have about a two inch flat mounting lip 
molded in. The wheel openings are flat with no lip or rolled area. We 
clamped the flares to the rear quarter panel and used a grease pencil to 
mark along the edge. We then drew a second line inside (closer to the 
wheel opening) about an inch and a half and parallel to the first. We cut 
the quarter panel along this second line, which left a big gap between 
the (outer) quarter panel and the (inner) actual wheel well. The wheel 
well is actually made up of two stampings with a seam along the top, sort 
of like a football helmet squeezed in from the sides with a casting ridge 
along the vertical centerline.

We cut the outside section of the wheel well, leaving about a one inch 
lip toward the quarter panel on each side. We then cut a cardboard 
template to fit from the wheel well seam on the inside of the quarter 
panel and cut sheet metal fillers to match, adding about 1 1/2 inch to 
the outside (quarter panel) edge. This edge had "V" notches cut into it 
every couple of inches and these "tabs" were bent up to be roughly 
parallel with the quarter panel. The flares were then captured between 
the quarter panel and the new flat filler panels, riveted, and filled. 
The inner edges were pop riveted to the lips left when we cut the outer 
section of the wheel well away. Everything was sealed with plenty of non 
hardening sealer primered and painted. We didn't weld the inner lip, but 
I think I would on a street car since that area is constantly exposed to 
water and such.

Yes, it was a lot of work and I'm not sure if I'd do it again. It does 
allow greatly increased room on the 510 with its semi-trailing arm rear 
suspension setup that introduces wheel movement in a number of different 
planes as the suspension works. Tubbing the wheel wells like this allows 
the use of 8 or 9 inch (wide) slicks without clearance concerns. We'll 
also be building a fully adjustable rear crossmember that allows 
independent adjust of camber and toe along with dropping the pivot points 
about two inches. Yes, this is a LOT of work and I hope it proves worth 
it, but in this case we want both the widest tires and the most 
adjustabililty. It costs much more when you want both.

On the '73 I plan to roll the stock lip inside the wheel opening upward 
and maybe pull the openings out slightly, away from the centerline of the 
car. Eventually it will have the same design rear cross member, primarily 
for the ease of adjustment. Would this roll and pull process be practical 
for your car?

I think the key to making things work without drastic body mods may be to 
go with a wheel like a Panasport that you can get in virtually any 
offset. While you may spend more more on wheels, you'll spend less money 
and time on body work, so you might be surprised that getting the 
"expensive" wheels actually cost you less at the bottom line.

At least on the roadster there are fewer suspension variables to deal 
with, but probably less room, too. Isn't everything always a tradeoff?

FWIW, Ron
