Has anyone used a 88-98 power brake booster and captainfab bracket? if so how did you end up hooking up the rod since its not threaded I didn't want to cut it and weld to it since it cost so much but trying to figure out what I should do I got a 87 master cylinder I wanna keep since its hooked to the proportioning valve using the brake system off a 87 since I have all the axles off of my 87 under my 65 so long story short will it work or should I try another one its the 2nd one I have had the guy at Napa is getting fed up with me since I keep bringing them back he just don't understand what I am doing
