DO NOT BUY! Magnum Farce 2" drop spindles are junk

On my GTS I had to go to a 4.75 back spacing on a 17x7 rim to get the tire (215/45/17) about ~3/4" inside the fender. The problem is Barracuda, Duster, 67-69 Dart, 70-up Dart all have different sized and shaped wheel wells. So what works on one may not so well on another. I ended up buying custom wheels to fit my set up of 73-up 11.75 discs and stock a body 8-3/4 with LBP axles and 11" rear drums. After hours of math, Tape measure and square and measure again I ended up with a 17x7 with 4.75 BS and a 17x8 with 5.25 BS for the rear (I wanted to run staggered). I know is sucks, I had to sell a set of rims that just would not fit and eat $1k for new rims. All because the track was widened and back in 1997 (back when Magazines and books were the information super highway) when I did my swap, none of the guides mentioned the track width getting wider either, with the stock stuff.
