Got it torn down today.

Good info. I wasn't aware that the 2732's were converted from 870's, which might explain why it pulls up as an 870 when they look it up.

I figured the only significant difference between the two kits is one will be easier to install the pistons but I wanted to be sure. I have to ask, since there were no shims installed with my older style liners, I would assume the 'old style' piston kit (no carbon scraper rings) would also not have any as well. All of my liners were at .006" protrusion. I figure that I could get a rather thin set of cummins brass liner shims and cut it to get back down to .014, correct?
