Alright I ordered it. cca-812-16. Question the journals are 1.869. Just got done measuring them. They are all within .0005. thats probably better than me so I was glad there but, Was I suppose to get one for a 400. In my book "haynes manual it says that 400's have bigget journal sizes? Is it just something I can tell the manufacter of my rebiuld kit and get bearings with a 400 od and the 350 id? thanks guys, it's going just slowly. Clearing up some confusion would be great.
