I have a 4cyl rearend that i want to swap out to a 97 gt rearend ,but the pressure hose that connects from the main break line to the rearend line is different is their a adapter i can use to attacth the new 8cyl hose setup.
Take the brake lines off the 4-banger rear and swap them onto the 1997 rear. You'll need to buy 94-95 GT rear caliper soft lines and bolt them to the axle and adapt to those using a Weatherhead 7818 on each side.
Keep in mind, adding rear disk brakes will require master cylinder change as well.
