Gear swap?

[Mark Rinker]

Anyone know who makes the rear for the C4500s? Wondering what it would cost to swap rear gear ratios from factory 4.88s to 4.10s or similar.

I think this answers 'who'...

This sure looks like 'what'...

Now 'where' can I find 4.10 gears for this rear? (Preferably used, or somewhere less than full over the parts counter retail...)
