I've never heard of that brand. The conversion bearings from Federal-Mogul are part number 1415SB 10, and the corresponding TRW part number is CB 503B-10. A friend who has been doing my crankshaft regrinding for a lot of years claims that the supply of US-made conversion bearings in .020" undersize has completely dried up. He can still get 10 and 30 under rod bearings, but no 20's.

One work-around for the scarce and extremely expensive conversion bearings is to use a rod bearing for a 3-cylinder Perkins Diesel and bore the rods to fit, and then grind the crankshaft to fit the bearings. The Federal part number for that bearing is 2015 CPA. The crankshaft journal size is 2.2485"-2.2490", and the rod bore size is 2.3950"-2.3955". The crank journal size is .060" smaller than a standard stovebolt rod journal, so a "worn out" .030" undersize shaft can be salvaged by grinding it to fit the smaller bearings. Also, the Perkins rod bearings cost about $6.00 each!
