There's plenty of rings in 3.810" all thickness are covered.

great.  Now that I got home from getting called into work.  I hope to take a look at the engine today.

Since we run larger than normal ring gaps, a set of 'filt to fit' STD would work fine in a .005" over.

when did you PM me?

that makes sense I haven't been on the other board in a couple weeks. I decided to go outside and work on my GN instead of laying on the couch and talk about other peoples TR's.  lol

at any rate the pistons are done and ready to go, I just haven't announced them since I'm trying to put my car back to turn key roadworthy, bang new chicks and do some home improvements around the house.

If you need a set I can fix you up, but you need to get a bore gauge in your block to see where they clean up at first.  Without an accurate OD, we would just be throwing darts.
