This is an original remanufactured crankshaft for MG Midget and Austin Healey Sprite models 1966-1974. This has been micro polished and is standard size on both the main and rod bearings. This crank has some pits on the journals, but the machine shop said it will not matter, you can get rid of them, but it would have to be turned 10/10.  This has a 90-day warranty and would be great for an engine rebuild.
