I'm finally almost done getting the hemi Challenger together. I'll finish the rear next week and it will be time for a driveshaft. I'm estimating 600hp with a 4:30 gear. 29/12 tire. 3800lb foot brake. I need to get a 1350 yoke. I had ordered one from Jegs but it was cast and I was concerned. I built the car to HOPEFULLY not break. Who sells forged or billet yokes? Or is it not necessary for this car?
