What propshaft would you guys recommend I purchase? I know of 3 shafts available for our trucks: Napa, Dynotech, and Brandon. I had web-link for Napa's propshaft, http://www.usfinancialservice.com, but it's not loading. So, I don't know the Napa part # or what the Napa shaft looks like (I'd imagine it resembles the original). Read good things in the past 'bout Dynotech shafts. I have all the 411 for ordering and shipping for Dynotech. And, Brandon makes a heavy duty shaft w.o. the double cardan joint. Were SyTy's built w/ a double cardan jointed propshaft for a reason? Can anyone give advise (disadvan/advans) 'bout these 3 shafts? I'm also buying custom made safety U loops, and replacing the torx bolts w/ hex head bolts.
