I have a 1953 88 diesel I am in the process of rebuilding the engin but I need main and rod berings but I need them in 30 thousandths under  and all I find are st 10's and 20's no 30 .I can find cranks but there is nothing wrong with mine but the bearings are wore .Would it be easier to find a different crank ? If so what info do I need and where can I find it?
