Hey guys, I'm looking into putting a hydroboost brake system on my 70 Cadillac deville. Aka "the Villian" I have noticed that when I look up regular brake boosters on Ebay that it says chevelle, camaro, nova. 9" booster also fits my car. So in theory the hydroboost set ups they have for these cars should fit mine. Has anyone ever used a brake booster from one of these cars to verify fitment? Or have hydroboost on their 69 or 70 Cadillac and can give me some tips? Thanks.
