SILVER Dana 44 axle/differential

SILVER Dana 44 axle/differential Got the "Differential Rebuilding" DVD from

Great DVD, it had normal and Trac-Lock Dana 44. Came to two conclusions:

1. I can do this... and
2. I do not wish to get all that equipment/meters et.al. for one time rebuild. Good investment, I now know the jargon, the methods, and the tricks. I found a drive train expert locally and found that he does it for about the same price as I could with buying the parts, consumables, tools and meters.

Here is my question:

ALL the differentials/axles in the DVD are painted SILVER!

What is the standard for Avanti? I thought it was black, did Studebaker repaing the standard Silver axles Black?

Is there anything wrong with painting my axle Silver?

thanks!
