Brake Booster Options

Should fit. I used a booster from a 74 Dart on my 65. Actually, I used just the stand-off brackets since I didn't want the rusty and heavy MC, so installed a booster and MC from a 95 Breeze, but of course the 74's would have worked on its own bracket. But rather than fool with old parts, you can get a booster w/ MC for ~$170 on ebay. They use an after-market GM-type booster with an adapter for the Mopar pedal, plus stand-off brackets and lever. Several posts w/ photos here if you search.
