Has any one ever had the problem with pulling the bolts completely out of the D60 spring perch housing? Pulled mine out threads and all the other day. Redrilled them and retapped them with 5/8" bolts. flexed out at Gray Rock and pulled them out as well. Went and got 3/4" studs but there's not much room on the outside of the housing. Has anyone had this issue and what did they do to fix it? I was running shims in the front before. 1 on one side and two on the other.
