Bolt in yj 8.8 assembly

I was wondering why i cant find any bolt on 8.8 assemblies for the yj,but they have them for the tj?
i realize a big part of the 8.8 swap is being able to create your own angle for your perches and such, but isnt there a stock yj width and angle that come pre welded so you simple just bolt the springs on and get the sye and flange and your ready for the swap?
or is there some reason im missing that this wouldnt work?
all in all i would mean a prebuilt assembly with the welded tube,shock mounts,and perches, so then all you need to get is the sye,flange to adapt it,and a diff cover that isnt made of tin foil

Make sure you read the fine print on the above 'bolt-in' axle.

It is Factory width with the same lug pattern. It Also Comes with Disc brakes, and has E-brake shoes built into the Rotor assembly. Compatible with your Jeep with new E-brake cables. The Jeep YJ Spring Perches are already welded on so you will easily be able to bolt in this axle assembly. You can choose exactly which options and upgrades you want for your new axle assembly. $500 dollar base price includes Ford 8.8" rear axle assembly with Jeep YJ Spring perches and shock mounts welded on, new HD U-bolts and U-Bolt Plates, w/empty center section but includes Used: axleshafts, carrier, yoke and all used brake hardware. ** All Axle tubes will be welded to insure they will not spin** Regear and bolt in. Or select from factory Gearing options for a minimal charge with and without factory limited slip. You can also choose to let us freshen up the factory axle with new differential bearings and axle bearings
note the highlights: looks like this is a used axle for 500 bucks and NO GEARS. it also says it is the same width as a YJ. that is incorrect. all explorer type 8.8s are more narrow. it states the perchs are already welded on, but where? it does'nt say they are welded to YJ width specs. I'd want more info from them. just my

'92 YJ, 4.0, 5sp, 8.8, Tera 4-1, SYE, BDS 5" on 35's. 4.56 locked F&R. <><
'05 LJR, 6" long arm lift, 5.13's w/37 MTR's.

The YJ is FOR SALE! PM for details.

I am also looking for something I can bolt in, I had seen the 8.8 from east coast gear supply,,,,,,but havent called them or anything. dynatrac advertises their trail series 44, and states that it can be bolted into a yj, again though, i have not called them to find out if this is actualy true. considering how popular the yj is, you would think there were more of these options out there. no offense to any do it yourselfers anywhere, but i dont want to be riding down the road at 60, or going up a steep hill with an axle that i have welded myself, not knowing if i got the welds strong enough or in the shock mounts or spring perches in the right place. i'd rather have one that was done by a pro and i know the welds are good and nothing is going to fail. because that is the point of putting a 8.8 or 44 in a yj, i dont want anything to break.

More interesting 8.8 stuff. Good points being made here. It just verifies the importance of doing your homework before buying. There are many ways this can be done to get what you want.
