And what was the length of the driveshaft? An accurate measurement within an inch or two? I build driveshafts for a living, i have been doing it 10+ years. The shop i work at has been building driveshafts since.....well since the majority of manufacturers started using driveshafts instead of torque tubes.
Nobody ever wants to listen when you tell them what needs to be checked to replace a 2 piece (or a 5" aluminum shaft for that matter) driveshaft with a single piece. I posted the calculator for people to do there own homework for there application and decide for themselves. Please do that folks.
