I need new shafts. I Just installed a 14 bolt FF + 3/4 ton 10 bolt and 38" tires. I aslo have a 454. Am I wasting my time with a 208 or should I be looking for a 205 before I buy new costum shafts. In the future I might go as big as 39" but thats about it. I do have a spare NP208 if this one explodes and I know there are tons in scrap yards if I need another. Who out there wheels with a setup like mine and how does the NP208 hold up? What are the chances that it will blow up with the power from the 454 and big tires? Also can you convert the front drive shaft on a 208 to fit on a 203or205 if I got new shaft now and decided to switch to one of these or a doubler later. Do you guys thing the 208 is a good alternative to a doubler because it cheap and the low range is kinda in between the doublers 2 and 4 ranges? Is this transfer case underrated? I know the 205 in super strong but is it even worth it if you have a couple free 208's already? + its a much better low range.
