At Corowa years ago, Uptons had boxes of Chev precision main bearings the local GMH NASCO brand . I bought quite a few of them but I havent been able to work out which years they fit . I have .030 and .040 sizes . I will take a few pics Mike

Thanks Mike,
I will be investigating further tomorrow, but it looks like the rods have been bored out and may not be true to the axis of the rod. Either that or rods are bent slightly. Will make a note of all shell bearing numbers as well, they are
-020"
