Source for Tundra Build Code Deciphering

Hello
Where can I decipher the build-chassis codes On all Tundras? Find rear end/gear ratio #’s to establish a baseline for 2004 4wd interchangeable rear end assemblies?
As well as many other parts interchanges by following MFR code

A03B is the axle code,
A750F is transmission code,
056 is your paint code
LB43 is your interior color code.


there is VERY little documentation for interior color codes for the first gen tundras. Maybe that's a task for this forum. hmm...

Axle codes seem hit or miss as well. It seems like people have the same axle codes but different gear ratios from factory. maybe we need come together as a community to figure this one out as well.
