What are these axle shafts acceptable too? I should be around 700rwhp. I guess i should assume i'm out of range for the stock shafts.

The reason i'm asking is, i'm using a 99 viper differential, converting the stub shafts to accept the TII inner cv joint, TII sized axles, and FD outer hub/cv. The reason TII axles are being used instead of FD is because the TII axles are shorter.

So really I could just buy driveshaftshop upgraded half shafts, but i'm having a problem locating just the 4 bolt inner cv joint. I'd rather not buy the entire axle assembly.
