Hey all. In checking out this great thread, I thought that the booster and master cylinder looked very different in my Blazer, and it is lol. I was looking at the part number to see what it might be. It has a penstar logo, it is Bendix 18268 with pat #3110031 "and others". So I cross referenced these numbers and according to what I found, the booster and master cylinder that was replaced ( by who?) is what they used in a '70 AAR Cuda and 69/70 Charger R/T
Anyone know why they would have done this? These days, a refurbished one of these boosters is big $$$. And then the original appearing master cylinder as well.
Just something crazy I realized and was hoping to get some thoughts.
