OK, so I've finally been futzing around with the steel 930 flares I'm attaching to my 72 RSR project, and some concerns have arisen.
I've read a ton of threads about how these things go on, and apparently I've missed the threads with the fine points on flare alignment. These flares WILL sit nicely against the contour of the quarters and front fenders - and at the same time decrease the height of the wheel opening. I'm going to run the car LOW, so I can't lose height in the wheel wells.
I've had to do some significant finageling (how does one spell finagle, anyway? Finaegle, Fenagel, Fenagle?) to make the flares "one" with the contours of the car and maintain the same upper wheel well lip height on the rear. Careful measuring against a customer's 930 verified proper front to rear and overall width at leading and trailing edges (although I allowed an extra 10mm width at the top of the rear fenders for a vintage look - see photo below)
On the front, I've actually had to rotate the leading edge upward about an inch above the top of the turnsignal opening (which would be the lower edge of the fender on an SC, etc.) to get the same height on the wheel opening. No big deal, I'll make a taller lower fender front filler panel to compensate.
Here is where I am gettting cross-eyed: The front flares want to lay vertical (the arch, viewed from the front) ala 930 (of course).
It seems that all the photo reference of the RSRs and STs show the arch rolling in toward the bumper in a significant diagonal, viewed from the front, as in the photo below...
It occurred to me that if I knew the width of the original RSR or ST from bumper, I could make my front flares land where they should (using the known width of my stock 72 front bumper as something to work from), and hopefully, get the diagonal taper close to accurate.
I need to achieve a proper symmetry to the front of the car, and I will be flaring my steel bumper to meet the fenders, so I need to be as accurate as possible here.
Anyone have advice/measurements for me on this?
