Pete, sorry you had a bad experence. As you know I have always had high praises for R&R. Now I feel guilty!
I have thought about the bed being 1 1/2" above the bolt holes in the fender and I just have to ask if the bed blocks are the right height? None the less, you should NOT have problems your having especially with the angle we discussed. I wish I had better advice.... now I'm reluctant to recommend them. It doesn't take away the pain but know we have all been there at one time or another.
Keep us posted on what you do.
