I have a 91Z28 350 car with the stock 10 bolt and drum barkes. Would a australian 9 bolt with disc be worth the swap and what else would I need for the brakes to work properly? Is the 9 bolt stronger and how hard is it to beef up if needed? Also how hard is it to get new parts for the 9 bolt if needed? Thanks guys!!

Did that swap last year with no problems. You will need the proportioning valve, parking brake cables and new brake line fittings for the B-W 9 bolt. Its stronger then your 10 bolt and I don't think you will destroy it unless its really abused.

 

Thanks guys!
