Big bolt lug pattern

Bbp axle/brake conversion (what I did):
Distance between the bearing and the axle flange is larger on bbp, need bbp brakes.

Or, Dr Diff makes BBP axles for SBP brakes, and sells new re-drilled drums.

Note: the A-Body axles listed on his website are 5 x 4.5.

Per Dr Diff:
Converting rear drum brakes from SBP to BBP

The A-body axles listed on my website will not fit stock 5 x 4" bolt pattern brakes with re-drilled drums, but If you leave me a note in the transaction, I will ship you a pair that will fit.

I can also supply a pair of new, re-drilled drums for $150 pair, plus shipping.
