On my 1982 the brake hardware is an exact match to the rear brake hardware on my 1978 Chevy C-10 pickup. chuck RQB-3553 I also replaced the rebuilt dual master with a new one that has a little bigger reservoir. It is a 1 1/32 bore, Auto Specialty 83014. I believe that my brake fade problems may have been due to the previous master. I think the increased fluid capacity may keep the fluid cooler and there is a possibility that the first one was defective. I had it for years. It was supposed to go on my 65 Monaco to convert the drums to disc but I sold the car. Ernie rizzolo Jul 2004 -
