With KG5512, 215-75R15 on 15x7 cop rims would not fit between Quarter panel at top of wheel well and brake drum/lugs. I had to disconnect lower mount of the shock to mount my tires. Returned KG5512 to RA.
(Knowing this is an older thread . . .)
PERHAPS, the reason for the different extended lengths of rear shocks as to do with "fender skirts"? Wagons did not have them, but "sedans" did. Maybe, maybe not . . .
Reading through this thread again, I remembered that when I put the P245/70Rx14 BFG Advantage T/As on my '67 Newport 2-dr hardtop, which has the Newport-size narrower rear brakes on it, that with both shocks still attached, I had to finagle the wider tire between the top of the brake drum and the quarter panel (fender skirts removed). They did not easily just slide over the drums. I remember thinking that if it had 11x3 rear brakes, I would have had to let the rear axle dangle on the springs, then reattach the shocks when done. NOW, the new BFGs were mounted on a set of 14x6.5" wheels I got from the salvage yard, which had been on a '65 Chrysler station wagon. I saw the car when it came in and then verified the specs for the wheels, via stampings on the inner area of the rim.
PERHAPS the 6.0" wide HD wheels, if they had a thicker-gauge metal on them, might have been the same price as regular 6.5" wide wheels. 6.5" wheels which would make rear tire removal (on Slabs and possibly Fuselage cars) harder to execute with the police/HD 11x3 rear brakes. Which would mean that these things had nothing to do with ultimate handling, but what would fit between the brake drums and quarter panels on cars that used or could have factory fender skirts!
