The only option is a machined down Viper input shaft.

isnt that the mainshaft? i am looking for the 31 tooth input shaft (4th gear) the main shaft looks okay, the input shaft looks like the weak link to me

The input shaft is where the clutch disc rides. Are you asking for a 31 spline clutch disc support? The input shaft only sees engine TQ and is good for over 1000. The gear(TQ) multiplication happens at the output where is can see several thousand lb-ft of TQ.

Yes its the input shaft. Its the same tooth count but thicker in the area from the splines to the seal surface of the gear. You have to have the Viper shaft cut down and machined to match the Ls1 input shaft.
