Hi JackHopkins,

If you give your local roads authority from your state a call (speak with technical section), they will give you the minimum legal requirement.

When I went from 173 to 350 Chev, I had an HZ Statesman that I got all my gear from. Transplanted the front discs and front end etc. to the van.

Nothing wrong with the drums already on there, they worked fine, just piece of mind for me...and to make it look good, and they were there so I changed them over.
