I have a set of D series Hastings rings, for a 0.020 overbore. Got the wrong ones and tried to install them before I realized they were bad. They are a little oily, I got them all on the pistons and THEN checked end gap when they wouldn't go in, stupid me. They are a little dirty but never used, put them back in hastings box. Looking for a trade, I need some stock sized rings for a D block. Located in Troy NY, sometimes in Durham NH.
