Chnging bolt pattern on rear axles

A little more help....

A conversion to the larger 5x4.5" pattern wheels that is somewhat common is redrilling the original small pattern axles and installing new lugs to facilitate a larger diameter wheel. The problem with this is that there isn't enough meat on the axle flanges to drill a hole for a regular splined lug and cap screws must be used. Racers have been doing this for years, so its not necessarily a dangerous move. It is safe to say that it is the most "un-elegant" 8-3/4" solution for A-bodies. In addition, the original SBP 10x1.75" brake drums must also be redrilled. You cannot use drum setups from 5x4.5" axles (No exceptions) with redrilled small pattern A-body axles.

Good luck
