5 lug convesion, rear rubber brake line???

[chev-obsession]

i have a 69 1/2 ton that i am converting to 5 lug disc brakes. i put the rubber brake hose that goes from the rear end to the frame on and it rubs on the shock absrober. i can not put it behind the shock absorber because then it will be pinched between the exhaust and shock. has anybody had this problem? what can i do to have the insurance that it wont rub through eventually? i can post a picture tommorow
