My take after a couple of glasses of wine, buyer beware! The spindle 3.27" locator and wheel 3.28" locator are an extreamly tight fit, with that said, I would not alter those dimensions, at this time. The locator pin 0.77" and wheel pin hole 0.77 dimensions are an iterference fit, although a very loose interference fit. What I would do is take the 0.77" pins thread them on to a threaded rod that can be placed in a drill chuck. Once threaded into the chuck, spin the pin and use sand paper or a fine file to take down the diameter of the pin a few thousandths, more so at the end of the pin and less at the spindle end, which should ease your fitting issues and not cause the fit to get to loose. Take it slow and do frequent trial fitting. Hope this helps.
