Hopefully he cut ya a deal on all 3, Definitely the older Dalton IN cast blocks, but still a deal if no serious out of the ordinary machine work is needed.
Third block is a Dart SHP 351 block. It’s for another project I’m ever so slowly accumulating parts. Have a TFS R upper and lower for it as well. Will most likely get a set of TFS 205 11R’s when the time comes.
