full or half groove main bearings

I've found very little selection for full groove bearings.

King makes a very nice looking set....they offer them in coated versions, too. The only problem is.....you can't actually buy them. I had a set on order for 6 months...the carrot they dangled continued to move out 3 weeks every 3 weeks. I finally cancelled them. That was after I took the time to call King and get through to their tech line, and the guy there said they were 'in the works' but also sounded like their level of urgency in producing these was a 1, with 100 being the best.

I have some Clevites that are full groove, but they are not the .001" looser race type, and I think there was one other thing about them that made them not as desirable.
