Exhaust Hangers (how many?)
 

I plan on installing my RB 13b Dual StreetPort exhaust system on my 79, but wasn't 100% sure on how many hangers are needed. I need a total amount from end of header->muffler. I really want to be able to buy enough from mazdatrix, so I dont have to order more later and keep playing the waiting game. Thanks in advance
