with limited net reading i thought the gears were different between the solid and irs, something about a bevel on one and not the other.

i mailed with richard and he felt 4.10 would be a bit much and provided information on the chassis that indicated 3.73 would be more appropriate. i'm going to run the 3.73 for a while and maybe later reconsider.

thanks for the input.
