I'm still running the stock drum setup frt. & rear .. No Problems .. Even when upgrading to a newer frt. suspension or just doing the disc only conversion all should work well together since the stock Rallys were 99% of the time always on a model with factory disc exactly like we end up swapping over to .. 2 whl or 4 whl drive .. There is enough clearance and depth , for rotor and caliper offset ...
