Roller Blocks
I made the mistake of fitting these believing they had been manufactured correctly! Unfortunately the fixing bolt hole centres were drilled incorrectly. So after fitting one bolt the second bolt hole was obscured. I needed to use the roller, so I had to remove the blocks, drill larger fixing holes so that distance between the fixing points would be correct at 155mm.
What a pain! I have photos if anyone doesn't understand the problem.
