Driveshaft and ABS ring specs

[lifespeed]

What diameter are our driveshafts, 3.5"? I am changing the rear suspension to a torque arm and need to think about possible driveshaft upgrade clearance, IOW should I leave clearance for a 4" shaft.

Also I have to machine an ABS ring for the new floating axle rear hubs. Any idea how many teeth are on the stockers?

Thanks,
