I got the perches from a local 4x4 shop. I had to grind on them a little bit to fit my axle tube. I think I paid $12 for the perches. Other guys I know have bought some online that are specific for the 8.8 tubes and are supposed to help with axle wrap. If I am in the sand and accelerate hard I get axle wrap. Google axle wrap if you don't know what I'm talking about.
I removed my anti-sway bar and just mounted the shocks to the open holes left. Others have bought shock mounting tabs and had them welded onto the tubes. If you use the stock u-bolt plates(just flipped over) and mount the shocks like I did, then you will need to cut off the old shock mounts so that they don't hit the shocks.
My friend tried to weld the perches, but didn't do a good enough job. So, I just tightened the u-bolts as best as I could and carefully drove to a muffler shop and let had them weld the perches for me.
The brake line needs to be extended. Since I have the drum brakes the T connector is on the pumpkin and was easy to elevate using some flat steel with 90 degree bends in it. I did at first use the stock brake lines, but they look bad, so eventually I just got some new ones and bent them to look ok. But, also had to get a tube flaring took kit cuz the brake tubes I bought at the auto store, the inner fittings didn't fit in the T connector and I had to reuse the stock fittings from the original lines.
And the home made clamps keep the load spring from moving and possible damaging tires or gas tank.
I think that's about it.
