[AT] Drawn out 1949 AC-B engine rebuild

[Mogrits]

Okay, assuming your comment about making shims is not referring to emptying
beer cans, do I have to replace the main berings or is that just considered
good practice "since you're in there"? These are the kind of questions I
have. Do I drop the crankshaft and take it to a (who do I take it to?) to
have it checked and ground and trued if necessary? Or can I just unbolt the
rod bearings and remove the pistons and sleeves, install new and if so, do
I install new rod bearings and how do I know what size to use? I am
assuming re-using rod bearings is verbotten.
