I\'m thinking Doubler for my 1972 K5, anyone do this yet>>>>>> Both my drivelines are toast from the Rubicon /forums/images/icons/mad.gif My rig is probly too fast for the Rubicon, even in Granny Low on my SM465 /forums/images/icons/shocked.gif SO The old brain starts a tickin....Doubler...Doubler....Doubler???? Need new drivelines anyway!! I did a quick look thru and decided to POST up my question. I have Sm465 4speed with Np205, I have the dual crossmember holding them up. Were is this technoligy now? I know there has been many 'versions' of the 'doubler', so wich one is best for me? Can I leave my SM465 installed and just pull the 205 and do whaever the job requires from there? And of coarse COST$$$$$$ So if you had a 350/SM465/NP205 sittin under your rig with no drivelines what kind of doubler would you use/get??? You = whoever has an opinion... /forums/images/icons/grin.gif /forums/images/icons/grin.gif Stephen??
