Wheels and Rims

I have a 1970 Plymouth GTX and I need a spare rim. Could someone tell if a rim from a Dodge Dart from 1970 with disc breaks and big bolt pattern fit my GTX with disc breaks and a big bolt pattern? Thanks.

if the GTX has 14's then yes. If 15's the calipers (Budd?) MAY require 15's. Others will chime in. Your 70 dart SBP has been converted to BBP?

If the bolt pattern is 5 on 4-1/2" then yes, it should fit.

A body cars, up to and including 1972, originally came with a 5 on 4" bolt pattern. If the Dart has been changed over to the larger pattern then should be ok.
