Differential hardware needed

I need all the ring gear bolts and 1 race ( race must be in good condition ) for the carrier and any extra shims you might have. I am not going to use these parts to build something to run, I just need them to practice building a differential. Let me know what you have.

Also if you have an extra solid pinion spacer for a 489 case I could use that also.

I know all of this can be bought new, but I just need used stuff for what I am doing.
