okay so i got some rear disc's off an rs integra, with a non abs brake booster, 15/16 master cyl and 40 40 prop valve..
im halfway through putting on the rear discs but i got tired of that **** and tried to put on the brake booster master cyl and prop valve but i almost stripped 2 of the screws....
i got one of the free though on the prop valve, but my question is how do i get those little 10mm bolts free without ****ing them up? pleas give me some advice someone... thanks
