I used a Precision brand part number 447

Anybody see this before??

I was able to get it moving under its own power again last night!! I'm just waiting on tire chains and wheel spacers to get delivered before I load up the weight in the box. It's almost cartoonish rake right now, lol. And 4wd works perfect, no scrubbing or binding or anything! Those gear...

Do you have any pics of the swap like in my thread above? What are you using it for? I'm still running 6-bolt tires in the front and 8-bolt in the back but you can see its more tractor than truck at this point, lol.

WHICH "14-bolt 8-lug" axle do you have? 9.5" semi-float, or 10.5" full-float? Both are "14 bolt" and both could have 8-lugs. With the 9.5, the existing driveshaft is likely to work. With the 10.5, I expect you'd have to shorten the driveshaft.

As did I, to connect the driveshaft to the 9.5" semi-float axle.

Daily ride. 10.5:ff. I've purchased the adapters to go from 8 lug to 6 lug already. Wld I b able to use the driveshaft out of the donor truck even tho it's a 2500?

See quote immediately above.

No idea. Maybe. My 10.5 uses a 1350 joint. I don't know what sizes the Precision 447 joint is, though.
