tips...
They sell brass adapter fittings to put a 3/16" brake line nut into the bigger sizes on most GM master cylinders,but they are costly,and diffucult to find at most parts houses..
I always save the original brake line nuts that are "weird" sizes or threads,by cutting the line off close to the nut,then remove it,--use a six point socket to avoid boogering the hex portion up!!...and carefully remove the peice of old brakeline inside the original nut..sometimes drilling ,or using a punch is nessasary to remove it..then you can slide it on a new peice of brake line tubing, and double flare it..
I've had to do this many times on a sunday,didn't have a choice really,if I didn't want to walk to work monday morning!...
If your real lucky,some places sell the lines that have 2 different fittings--one fits the master cylinder,the other end has the usual 3/16" line nut..best to bring your original lines from the master cyl. with you,because there are many different thread sizes used on them..you may end up using the old fittings,because finding the right ones in stock at a parts store is a crap shoot..
