I have a aftermarket (looks like a gm) master c yl and power brake booster installed on the charger. I bought new one type pre bent stainless 3/16 hard lines. From inline tube. All that stuff was great. And on the car
Mopar uses a large 1/2 fitting on the line that threads into the m.c. problem is my new master c yl. Uses,s small (metric?) Thread fittings. I can't install my lines to it
Any guys on here run into this?
