Where exactly on the crank and block are the numbers and letters I need to be able to get bearings. My local shop has been working with a shop on this board (name withheld for time being) to order bearings and the only numbers they have been asked to provide are these:

Block: 212122
Crank: 211112

It's been several months now and all I'm waiting on are bearings so it makes me think that the shop on this board is not doing anything on this. They also need some letters, right? Where would they find those?

There are a series of letters AND numbers on the block.....its stamped on one side...top surface...so its visible when looking down on the block. you cant miss it.

The numbers and letters on the crank or on the last counterweight on one side of the crankshaft...again...you can't miss it.
