hi everyone. first timer here. im in the process of takin apart the rear iso on a 69/70 frame. it already has mk111 ones in it. i bought another mk111 kit replace it. ok, ive finally managed to remove the rear engine mounting stud and just have the rubbers to remove today. now my problem is that the mounting stud measures 0.5 inch (12.66mm) across. and the inside of the new iso tube with the rubbers on is 0.54inch (13.66mm) is this amount of slop right as it seems way exessive. the frame holes for the bolt are a good fit. all i can think of is the latter chassis has a larger bolt maybe. or someones made my new one too large internally. hope someone can shed some light on this for me. thanks, john.
