Need stock 318 flywheel for 70 dart

LUK part number LFW215 should fit the bill nicely. It's a whopping $64 on RockAuto brand new. LUK only has it listed for 318 pickups for some reason, but their cataloguing is notoriously bad. It's a 130-tooth 'wheel, same as a car, and there's nothing different about a truck 318 (2WD bellhousing, starter, clutch, and throwout bearing are all the same). Don't know that I'd use it with slicks and Cal-Tracs, but for a driver? Hell yes.
Using the old Direct Connection diagrams, a machine shop can "unbalance" it for 360 and external-balance 340, 383 (1971 cast crank), 400, and 440 applications. I had one done for a 360. It cost more than the flywheel!
