Tj sbc swap---sye question

I have a 99 tj---just bolted up a built 305 sbc, with a nv4500 and a np241c transfer case. Now my problem is my rear driveshaft is only goin to be about a foot long from yoke to yoke. If I instal a sye kit on the 241 will that get me back to stock driveshaft length? I don't have a stock driveshaft to use to measure it. I'm hoping the sye will solve my problem but I'm not sure. I know somebody else has done this so help a brother out if you know anything about it!

A regular SYE does not change the output shaft length. A super short will shorten it a few inches.

JB conversions has a Super Short SYE looks like you'd gain 9 inches and you'd be fine. If not the next move is to stretch the rear.

NP241c is stupid long and a regular SYE dose shorten it up good bit.

Yea it's out of a 3/4 ton Chevy. Thanks for the help. I was planning on buying the super short one from jb conversions. Does anybody have a idea on how long a stock driveshaft is? And does a stock driveshaft have a slip yoke/cv joint or whatever you would call it?

Stock does not have a slip yoke. You will not be able to run it with an SYE

Thanks for the help fellas. Looks like I'm gonna start ordering parts tonight. How hard is a sye install? From what I can see it looks fairly simple.

The SYE is easy but the Full circle clips are a pain the auto store pliers won't do it. I had to put my jeep on hold for a week after i trashed two of the auto zone cheapos, i found a nice pair of c clip pliers in my Grandpa's old toolbox and the rest was smooth sailing. So before you start make sure to buy a nice pair of c clip pliers, make sure to pry the case apart on the designated points, and take your time and it'll go fine.

It's very easy. Just get a set of good lock ring pliers.
