Piston Rings

[Volvoist]

What piston rings (brand) are the best to use when rebuilding the D24? I am planning to use the OE style spring type, but wanted to see what those that have rebuilt the D24 have used, where they were purchased, and what their experience with them has been. I am not there yet, as I need to open up at least one of my motors to see if it needs to be bored out. I am hoping it will just clean up and can be re-ringed. We'll see...
