I also have non, my plan is to make a plate that will bolt on top of the spring pack to hit the bump stop. It may need to be braced back to the spring on an angle or have a suport going down to the axle, but should be perfect length, and not have any iterferance issuses.

bumpstops will help your flex if measured right. just think of it as a pivot point for the axle. when one end of the axle goes up and hits the bumpstop, it will force the other side of the axle down.

Plus your springs will last longer if your over-compressing.

Jeep sells factory bumpstops in 3 or 4 different lengths with the longest ones being about twice the height of the stock XJ bumpstops. The long ones can be found on junkyard MJ's.
I bought some new ones at the dealer and don't think they were as much as the poly ones, but don't remember for sure.

Dirk at www.dpgoffroad.com has recently put into production some adjustable rear bump stops. They work out pretty slick and are now available.

Not true. He does need them, and so do you.
The bump stops do two things. First, they prevent the tires from rubbing the fender well liners. Second, if sized properly, they prevent the springs from compressing too far. This saves bent springs, and helps keep the springs alive a lot longer. A lot of the complaints we see on this forum about springs that sagged in no time at all are the result of over-flexing the springs.
As noted, there are four sizes available from the factory. The dealer's parts catalog will not know which one belongs in which vehicle, but it should list them by height. The tallest is the one that was used in the 2000 Up Country. I have a set in my '88 stock (non- UpCountry), and with no lift I have about 1.5" to 2" clear between the axle tube and the bump stop. This may help explain why at 238,000+ miles my rear springs haven't sagged -- at all. I know I sometimes hit the bump stops, but my springs can't over-compress.
All four sizes are also available through Crown. If you have access to a Crown dealer, their stuff is usually about half the cost of factory and usually just as good.

Well there is no doubt I need them that I knew. What I did not know was that there are three different sizes. So unless someone on here has some to give away. 
I'll be either going to the U-pull it soon or checking the other options.

I recommend against going u-pull for these. Here in the rust belt it's unusual to see an XJ more than a couple of years old that still has rear bump stops. The mounting plates rust away very quickly. I know you're from the south and you don't have much snow and road salt to deal with, but you have rain and mud. For what you save going used, I think it would be a shame to buy 'em and put 'em in just to find they disappeared a few months later.
Besides, unless you find a late model with Up Country, you won't find the tall ones in a bone yard.

Ok, I'll look into some new ones then.

Junk yard MJs? Didnt know those even exist, have a hard enough time finding XJs ehre much less an MJ.
I just bought some square tubing that comes prdrilled, I will be using it to make a spacer for the factory rear bump stop. Bolt it to the original location, bolt the bump stop to it...done.

I measured once, 86 longbed IIRC, and the rear bumpstops were the same length as the ones on my XJ (not very long). So not all MJ's have longer bumpstops.MaXJohnson said:
And even out here in Colorado (what's rust
) I've seen plenty of XJ's and MJ's where the rear bumpstops had rusted off. Sometimes I see it where the rubber just flaked off in layers, no idea why.
