Hey guys I'm building a 24" chain drive drop box, does anyone know where to buy  some    1-3/4"-10 spline shafts? and possibly some sprockets splined to fit the shaft. I found that Power pro racing products sells them but i cant get a hold of anyone there. What other suppliers can get these shafts?

You'll have to have them built. At least that is what I did for my shafts when I built my box. Make sure you use 4140. Bought stock, cut them to length and then had a machinist do the splines. Can't remember if he broached or hobbed the splines. But I do know that he had to rent the tool to mate up the 2.5 ton yokes that I used. That spline is very old and uncommon now a days.
