    I just pick up a np205 and it has a yoke-style front output...What is involved in swapping this out in favor of a flange? Thanks....

    actually the yoke is supposed to be the better one
    real spicer style CV rather then the saginaw style flanged one
    heard it allowed more angle
    I like the flange for easy removal

    is the cost to have a driveshaft built for a yoke similar to the cost of a shaft for a flange?

    should be the near the same, I would guess
    you would have to call Jesse or someone to find out for sure

    I've been told the flange front output is the stronger of the two cases...

    I guess max angle is important with a tall lift, but in my truck I want strength...

    I went through this on my swap. The flange from the 208 wouldn't fit the 205. I took the flange I had from a 203 and put it on the 205. they had the same spline count. Before I could get the driveshaft shortened, A buddy gave me the shaft with the CV for the Yoke. It definatly looks stronger than the flange on my 208 shaft. The metal around the the ujoint on the flange is pretty thin.
    When I was looking for the flange to fit the 205, 4Xheaven quoted me about $65 for a used flange.
    The actual swp is simple. Only one nut. It can be a pain if your T-case is out of the truck and spent the majority of it's life in the rust belt. An impact wouldn't budge it. Used 2 6 foot breaker bars and a lot of ass to get it busted loose. And I probably will never use it. LOL!

    I'm thinking of switching to the 32(?) spline output from a Ford and then getting a 1410 u-joint yoke and matching shaft for it from Jess.

    Ive "heard" that the flanged yoke is stronger too... I tend to prefer it either way.

    as for swapping, you will almost definately have to swap the guts of the two cases because when I swapped input gears between my 205's, one was flange front, one was yoke front.. when I had em off, I tried to fit them on the other case and they're way different.. it was a 73 and a 77 np205, dont know if it makes much difference...
