    my drive shaft won\'t work

    I've just installed a 14b ff in my blazer out of a 77 3/4 ton and of coarse the yoke size is different does anyone know of a mismatched u-joint I can get? when I ask about one at my locall parts house they look at me like I am an idiot. A part # or something would help Thanks

    I think the napa part for a 1/2 ton to 1 ton conversion joint is a #447. I think 3/4 ton driveshafts are the same as half ton, so give it a shot.

    I started with nothing and I still have most of that left! - <a target="_blank" href=http://community.webshots.com/user/borregok5> Pictures</a>

    Mine took the Napa # 348. It's called a bastard joint.

    Precision U-Joint #448 worked for me...
    Best of luck I know the frustration...until you find someone that knows their stuff (very unlikely behind most parts counters) its difficult to locate one.

    Definately a pavement pounder...with the caveman clutch
