1970 Plymouth Belvedere Power Brake Boosters

Much longer than the single diaphragm unit that was in the Dart originally but the new unit fit right in with just two issues. The bolts holding the booster to the bracket are larger than the originals so the extra supports going from the bottom left bolt to the firewall and fender well needed to be drilled out. Also the original bolt connecting the brake pedal to the booster arm has a shoulder on it that does not fit through the new piece. A new bolt needed to be installed there. Overall, I am very happy with the purchase. Part is high quality, delivery was much faster than expected, part was double boxed to make sure it made its way to me safely, customer service answered my question quickly and the price was right.
