A simple question about MB part numbers, MBZ, M22?

[mookschank]

Ok here goes, 1st time post (so take it easy) about perhaps a really obvious question out there.

Been wanting to buy some parts off Pelican and I can see MB part numbers with either MBZ or M22 designation at the end.

I have searched around and have no idea what they mean? Thought it could be OEM or 2nd tier Supplier or something.

Can anyone help out or explain what this means? (Because if it doesn't really matter, the parts I want will be cheaper!)


Thanks.
