6 lug 3/4 ton?

Ideally, having driveshaft modified is your best bet as Dneel81 said. But my 97 came with a conversion joint. I played hell trying to find one because parts store kept giving me the wrong joint and saying it was the only one available for my truck. Had to go to the stealership to get it. But I have a needle in a haystack as its a 97 K1500 but it was ordered as a camper special cab chassis. It was originally an extended cab but went to a company called Centurion Conversions and they extended the frame and put a full rear cab on it making it a 1/2 ton crew cab which wasn't available from the factory in 97. It's a 350/4L60/241 with a 14 bolt semi floater. Well was anyway. It had a transformation about 5 years ago.

Anyway, here's a good write up I came across describing the swap. Read thru it and all of your questions should be answered. I cannot find my old receipt with part number when I bought my u-joint. Hope this helps.

4l60 pushing 40'' ground hawgs? Whats your ratio 4.56? That thing looks like it needs a a Big Block or a Diesel pusher!

True that. I didn't know they made such sizes.

If I'm not mistaken they are 47" I'm not all that sure though....yeah I'd have a big block in that thing atleast

 

[YukonandtheHOE]

Yah with a 350 that thing must be a slug.

 

[kyle Loosemore]

They are 40s I think

Hahaha. No 350. No 4D's. 496 and they are 49's. Engine is out right now. Building it up a little more and bullet proofing the TH400. Searching for a drop box and swapping the 60/14 to top loaders and links. 5.13 gears in the 1 ton axles. 15" lift and going 4.5" more to clear these 49's.

 

[kyle Loosemore]

Dude you gotta let me know when that's done I'm drooling hahaha

Bench is 48" tall and that's my 80lb bulldog/boxer if that gives you a better idea.
