Leaf spring relocation - shackles to frame
Backspacing needs to be around 5.5" with an A-body 8 3/4, 15x8's and 275/60/15's. Has to have offset hangers/shackles. Most cars need a little trimming/rolling at the quarter lip, but it can be done with the stock tubs and just a 1/2" offset. The backspace has to be pretty much dead on, and there's no extra room. But it can be done on most cars. As I'm sure you know some of these cars have less room than others because of body tolerances, so some cars need some quarter lip trimming, some may not, and some may not be able to manage it without rubbing even with some trimming. It's pretty much right at the limit.
PowerSerge's car. His only has a 4" backspace but he has a shortened axle. Doesn't matter if you get the right backspace 67-69 Dart...275/60/15 drag radials...how low is your stance?
Rpmagoo's car, 275/60/15's. He says he has a 4" backspace, so, must be a shortened axle. But again, doesn't matter if the backspace is correct for the axle width [URL="http://www.forabodiesonly.com/mopar/threads/largest-rear-tire-on-stock-wheelwell-69-dart.361656/#post-1971409206"]largest rear tire on stock wheelwell 69 dart[/URL]
GmachineDartGT's car has 275/40/18's on 18x9's. He has an A-body 8 3/4 with BBP axles. 6" backspace because of the 18x9's. Latest tire 1970 Swinger with mopar off set shackles can I fit a 275 tire?
There's a few other folks that have done it, and a few guys that are running 275/60/15's with stock wheel tubs and a 3" spring relocation too. Thing is, the stock tubs are more limiting than the springs are after a 1/2" offset, so, anyone with stock tubs and 275's can be used as an example.
Roccodart440 has that set up, stock tubs and 275's with a 3" offset.
That car has already been mini-tubbed, the tubs are in line with the frame rails. With the stock tubs there's an overhang, there's a couple inches from the rail to the inside of the tub. So with yours I'd just complete the 3" relocation.
