I need some advice regarding what company you would recommend by experience for building a 3 1/2 inch aluminum driveshaft for a B-Body Mopar. I am considering PST, Mark Williams, and Denny's so far. I want to have one built using a Strange U1666 1350 U joint trans slip yoke I have already. Goal is to have the driveshaft be high speed vibration free, strong, and reliable for a long time. Needs to be able to live with 505 stroker 620 HP/TQ in 4000 lb street/strip car with driver. Best bang for the buck and warranty are also big considerations. I would like to keep the cost down around $400 for the new aluminum driveshaft. Happy Thanksgiving !
