Heard you can redrill em or you could just get new axles for it if you wanted to have an all gm pattern...

There are at least 3 different bolt patterns. None of which are the same as F-Birds or GTOs. You can however remove the studs and have the axles redrilled.

Big car is 5 on 5". Fullsize Rally IIs will fit that pattern (had them temporarily on a 74 LTD before).

The three Ford 5-bolt patterns are 4 1/2", 4 3/4", and 5". Some stock Ford axles have protruding "register" diameters that may concern you, but I don't remember the details- might have been only the 28-splines.

Ralph,

Moser can re-drill your axles to use a Ford drum/wheel. Or get a Ford drum, take the wheel studs out and mark inside the drum where the GM bolt pattern would be, and drill them out on a drill press.

I am using a disk brake setup. T/A rear rotors, a metric caliper from a Cadillac, and a disc brake bracket.

Bracket link

This setup just barely clears on my 15x10" wheels. The E-brake bracket needs to be tweaked to work, but wouldn't be an issue on a 15x8" wheel.

Always some disagreement about bolt pattern numbers.
The illustration from Wheel Vintiques shows an easy way to measure the odd-stud-number pattern, but it gives a figure about 1/4" smaller than the diameter of the circle shown.
A 4-3/4" bolt circle, which is what the usual GM wheel is, will measure 4-1/2" across the studs, but it's not normally referred to by that number. The size is the diameter of the circle.
Most post-1948 Ford cars (and Chrysler products) use a 4-1/2" circle. Some of the big cars use a 5" pattern, same as a B-body GM. Ford pickups used a 5-1/2" pattern from 1928 until a few years ago.
So the real answer to your question is, "it depends on what the rear came out of."

Heh. That's probably a 5" pattern, but it might not be. Those are heavy old 'Birds. Got the disc brakes on it?
