Building a new 505 With Callies / Mopar Performance Block

If you need clearance can you sand the ends of the spacers? There are ways to effectively do this. I used a steel plate and 500 grit to hand sand an oil pump body down from .004 to .0015 end clearance. It takes a while, and care must be taken to do it evenly, so you need a caliper to keep track of how much and how even your progress is. On bolts, a good hardware store ought to have what you need, or an industrial supply house. This stuff may be a pain in the butt, but it seperates the men from the boys! Hang in there, this deal is going to rock!
