I have 4.10's and love them.

I really like my 4:10s too, especially the way 6th gear feels on those long Texas highway cruises.

The gear is a 3.73 - not "something like" X.XX! your wheel/tire choice was a "known" and is something that needs to be considered when "selecting" axle ratio.

It seems originally the gear change was to be a "dual purpose" install, performance (you've accomplished) and speedometer/odometer "correction" (you missed it seems). What now? Speedo/odo was slow?

SPEEDO CORRECTION:

If your car actually had Marc's 4.10 drive/driven you're in good shape. You've got three driven gears available to you before you would need to change the VSS 40, 41, 42. I see your reference earlier to the error so I'd probably attempt a 41 tooth (25513048) first.
