I am swaping ls1 disk on my car and i had planned to swap the ls1 booster and master for a matched set. I modified the booster to fit but the master has metric fittings on the engine side. I would like to get standard fittings on the fender side.

if i can get what i want dies anyone have a guess at what adapter fittings i will need to make the ls1 booster connect to the 69 brake lines?

I swapped in the same exact master booster combo in my car. I took the original lines from the LS1 master and cut one end off and reflared it with the fitting for my cars distribution block on it. That way there are no adapters.

Go to the brake section and I am sure the info is there. I believe adapters are available that convert from the bubble flare(ls1) to the double flare (69) but I have no idea on the specifics.
