73 dart swinger power brake booster

Yes, I saw a complete new booster/MC/brackets/rod on ebay for $136. A narrow 8" booster that fits easier, and not the GM booster conversion kits you saw previously. Hard to beat that. Don't make the mistake of buying just an O.E. booster, assuming you could find one (getting rare). An A-body also needs the special stand-off brackets w/ lever and NAPA never sold that.
