Simply measure the distance between centers on two studs not adjacent to each other. Or try a wheel!

With the exception of the small bolt pattern A bodies and 1966 down Imperial: all Torsion bar Mopar cars and 5 lug 2WD trucks (to ca. 1985) till 1989 used the same 5 x 4.5" pattern.

I can't measure the wheel bolt pattern, the car is not local to me. That's why I asked here.

With the exception of the small bolt pattern A bodies and 1966 down Imperial: all Torsion bar Mopar cars and 5 lug 2WD trucks (to ca. 1985) till 1989 used the same 5 x 4.5" pattern.

I figured it was likely that it used the same, but with cars like the Imperial having a different pattern I'd better confirm it.
