Default Should I Buy this SYE (HnT?) Kit - Advice?

Found someone selling what he calls a SYE kit, but linked me to this page here, which I think is a HnT. I'm still learning this stuff. I'm about to bastard lift my '01 about 3" and he's selling this for $50: "The only thing I am selling is the sye, its comes with all the hardware and it is currently attached to a np242 with something wrong with it. No driveshaft."

Should I bite?

The RE1807 SYE requires the modification of your stock output shaft. Drill and tap included for easy installation.
Taken right from the RE site.

FWIW I like the HnTs better.

You can move the HnT to another tcase easily. If you nuke your tcase with a 'true' SYE, there is a chance you ruin the SYE. Not the case with a HnT.

Lots of folks fun them here and have NO issues.

So besides what is included in the kit, what do I need? I mean, do I re-use my stock DS, do I need nuts and bolts, and little things, or is it good to go? Is the price good, assuming the product is in good condition?

I wheel my trail rig with a HNT, no issues yet. The kit is basically a yoke and some bolts, but at $50 that is still a good price if it has everything. The older TCs (pre96?)need a flange to seal up the output shaft once you remove the tail cone, but you should have the newer style TC so you won't need that. You will need some way to cut down your output shaft (grinder), some good drill bits and a good tap. Other than that, it is a pretty straight forward install. You will not be able to reuse your rear driveshaft. You need another front driveshaft to put back there.

Can I use a front DS with a NP231 and a D35? I've read it's too short.

The rear axle has less to do with the front shaft than the trans itself.

A longer front DS comes from a truck with a longer trans.

So its really a combo of numbers. What did the donor vehicle have for a trans and Tcase? And do you have a manual or auto trans with your D35 rear?

Measure it. I used the one that when compressed was 29 3/4"ish (IIRC). I do know that it came from an XJ with a 242 behind an AW4.

Mine: 2001 XJ, automatic, NP231, D35.
Donor: 97+ XJ, unknown tranny, NP242, unknown axle.

He isn't including the driveshaft, though, so I would need to buy one no matter what, right?

Yes, you will need one.

Thanks, Frank. I lost that link, but I'm trying to make sure I know what I'm getting into because in that article it says:
For starters, I can only confirm that this will work if you have a 4.0, AW4, and 8.25 rear axle. From what I’ve learned if you have the D35 the shaft will be too short in which case you could have it lengthened. I have never tried this on a D35 so maybe someday someone will and let us know how it worked or didn’t.
Trying to keep this as cheap as possible, and lengthening a drive shaft doesn't sound like the most cost-effective way to make it work. Maybe I'm wrong, though?

I hate to rain on your parade, but would seriously consider a new DS at the very least. Sometimes it's possible to get a local shop to set one up for you for not a lot of money. I definately don't want to discourage your junkyard raiding as it will definately yield the cheapest option.

I've had to drive around on my front shaft alone for almost two weeks while saving/waiting for my SYE and DS to get in (tomorrow).
