hi everyone, sorry i haven't posted in a while, working 7 days lately. i took your guys advice and bought the hedmans for my 70. you guys were right, nice fit. right side slid right in. on the left i had to remove the z-bar and motor mount bolt and jack it up. best part is all i had to do is weld about 9 inches of pipe to the collectors and they slid right in to my pypes exhaust!!! so i got to use my exhaust and not have to get another one!! now i wish i put down the dynamat!!!! thanks again!!! retro sound radio next!!
