I'm looking to do a brake upgrade on my GF's 79 CJ-7, but had a few questions that I couldn't find clear answers on after searching. First the CJ-7 already has the stock CJ brake booster, my question is does a Master Cylinder from a 86 Ford E350 directly fit the stock CJ brake booster or is does this master cylinder only bolt to the YJ brake booster? Same question for the 78 Mercury Marquis and 69 Chevy Corvette Master cyclinder as according to my searches these also might fit the stock CJ brake booster. Also from what I read the 95 YJ brake booster is the only year that was dual diaphragm and therefor better, so is a regular YJ brake booster that much better than the stock CJ brake booster? Thanks in advance for any help. :cheers2:

Thanks again,
Fred R.
