My converter bolts are short that I got with it at 1.250" long so lucky I got some at summit that are 1.5" but the bolt is about 1 thread away from hitting the front cover of the vert so I think I can use it.I did not tq it to 60ft lbs but if it hits then I think I can grind a tapper on the bolt so it will clear.Look at the vert bolt pad and the front of the vert and maybe you can see what I mean.
