Crankshaft bearing replacement

[elrichartl]

Hi everybody
This is my first post, I’m from México, I’m rebuilding a CB750F 81’, I need to replace crankshaft bearings, I bought some in ebay but they’re not fit , so, did you replace some of those, what are fit for my engine? is there any place to buy those that could deliver to Mèxico?

thanks in advance

Welcome...other members may have other information but I'd think Silvers USA. Seems like a few OEM parts are still available, including bearings sought.
