Hi all hope someone can help. My front drums are past their used by date. I purchased two new ones. Used a stud cutting tool and pushed out the studs from the hub, removed hub. Purchased a set of new studs. Now my problem is, the hub center should be a snug fit into the new drum to center it when pushing new studs in, I have a gap, is the center hole in my drum is too large but stud holes do line up. Also my new stud knurls will be a snug fit going through the hub, but it will not be when going through the new drum. So the stud hole are larger in my new drums. Has anyone experienced this? These drums are from someone that has dealt with skyliners over the years, so I guess they are correct, Has anyone put new front drums on their 57 skyliner and if so where did you get the drums and did you have any problems with hub swap? Love to hear from someone as I am in desperate need of help. Thanks
