I'll explain it the best I can since I havnt installed all of that on a Bump yet. But most will roll over from the 64 install modifications to the bump. Im glad to note that I had to do ZERO modification on the 64 at all. Just the parts.
*I had to bore out the single MC holes that Bolt to the booster. (Out of curiosity I tried my old manual dual MC off my bump to see if it will fit. And it was the same. U can either bore them out or install a chevy MC)
*I had to drill 2 holes In the universal bracket so that I could use the existing bolts on the fire wall.
*I had to cut the adjustable push rod an inch shorter to fit the pedal hole, so that there wasn't any interference.
*Last though not a modification, I had to pull the pedal assembly rod out to install the adjustable push rod on the the pedal then re-install the pedal assembly rod.
That's it. Easy
On a Bump it could be less or more. I'm thinking less mods.
The hardest part was boring out the MC holes.
On my bump I'm going to use the oem none cantilever-style booster brackets.
Despite the 3 modifications this install is worth it. Those boosters are fantastic. The truck stops great. Better then any oem reman. My dad is still calling me telling how well it stops.
Hope this helps
