Drive shaft question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1972 GMC 3/4 ton that had a 402 with a Muncie 4 speed with granny gear. I swapped it out for an 5.3 LS with a 4l60e. The truck has a two piece drive shaft. The original 4-speed had a bolt on yoke. The 4l60e has a slip yoke. Is it okay to use a slip yoke on a two piece driveshaft? It already has a slip joint between the carrier bearing and the rear end. The carrier bearing is mouned in rubber. Will that allow too much movement? Anyone have experience with this issue?
Thanks
