Planning a little engine swap into the TJ next summer. Only 2.5 inches of lift with stock style control arms. No plan (yeah I know) to do much more in that regard.

The question is has anyone ever ran a slip yolk-double cardan driveshaft? Plan is to use the 4.3 (don't want to hear it!) I'm building, I have an NV3500, looking for a manual shift NP231C from an S10 and trying to avoid the cost/hassle of doing a SYE on a Chevy TC. Here is an example of the driveshaft I'm talking about. Says blazer, pic is for Jeep... http://www.driveshaftsuperstore.com/blazer_rear_drive_shaft.htm

Also any other information or suggestions on anything that could be a bolt up for the Chevy version of the NV3500 would be appreciated.
 
Sorry I haven't but I have done a 4.3 vortec multiport with a 4l60-E and the chevy transfer case in my YJ, and mine had a fixed yoke. I am not sure what the differences are with Chevy, but maybe you can find one from an automatic that will work on your manual?

Other than that I have not used a double cardan with a slip

Also stick with the manual you will be much happier. Mine was a pig with with the automatic. I mean it was OK but I was sad I didn't V8 it. I might have been happier if I left it a manual.

lastly be careful with the fuel lines when cutting out the old motor mounts hehe

If you find a 231J with a fixed yoke that may just bolt right one too. Not positive but worthwhile checking into?

Too easy. Make your own. Some say, “if you want it done right, do it yourself.”

Obviously you can use this to build a custom dc slip yoke shaft yourself. It may require some work. But I think if you're swapping an engine this should be easy.

Thanks for the input you guys! I had considered just making one. I guess what I'm thinking about is with only 2.5 inches of lift and the option to basically give myself a "motor mount lift" when installing the engine to help reset the drive line angle, should I even be worried about an SYE, and if anyone had used a double cardan slip yolk DS, is it even worth it due to it's length.
