If there's enough of a demand for the single-piece seal modification, I can build an adapter for my Van Norman cylinder boring bar and provide that service. Counting the cost of the seal, and setup and machining time, it would be about a $150.00 procedure, plus shipping to middle Tennessee. I would need the bare block, with the rear main cap installed, to do the job.
