big bolt pattern
Another way the FMJ spindle height is helpful:
When building a big block or hemi A body (even some smallblocks with tall manifolds) it is common practice to use K frame spacers (like the factory did on the '68 SS darts and Barracudas) to keep things tucked under the hood, or at a desired level.
The added height of the FMJ spindles helps keep geometry from getting too out of whack.
when searching the pic and pulls, what other cars can you take parts from to make a 67-72 a body big bolt pattern? and what do you take off? say a diplomat, aspen, volare or m body cars?
For the rear, an 8 3/4 from a '70 and earlier B body is only about an inch wider per side, easily worked around with correct offset wheels, and sometimes not even needing that- depending on your body style.
F body 8 1/4s also fall into the same width range.
Both are becoming tough to find, though.
Early five bolt Dakotas and Jeep XJs may also have 8 1/4s in a similar width range. A tape measure is your friend here.
A much more available (and probably cheaper, too) option, as distasteful as it may be to some, is the 8.8 rear from a Ford Explorer (which can also get you factory disc brakes, limited slip, and gears in the mid to high 3s):
8.8 swap
