Prothane Cab Mount Question

[wayno]

So I'm finally to the point of setting the cab back down on the frame - big day - I had picked up some prothane cab mounts - I expected to drop these down into the holes in the frame but the diameter of the raised piece doesn't fit down into the holes - am I missing something?
This raised portion should fit down into the hole in the mount right?

can you ream the holes larger to accept the new mounts,? you got to love the after market but without them these trucks would be harder to build.

I bought the prothane kit about 3 years ago never installed them. I was able to mount the cab but the RAD mounts don't fit the frame are smaller then the bushings like you had. I was thinking about drilling them out but worried it might throw off the fender alignment. Did you ever get them to fit?
