Cleaning out the garage and came across these. They have been lightened, ballanced, and have new ARP bolts in them. The machinist was Bob Beer, who passed away about 8 years ago so I don't know everything ab out them, but I do know Bob did great work including making some of the early billit rods for TA. They were part of a car deal where I got bunch of misc parts. One of the boxes had some scribble notes on them if you can read or understand them. They have been sitting around for about 10 years. Buyer will pay actual shipping from 98908. $250 takes them. Can call with questions (509)945-6010 Jim
