Actually, the cut and turn of the KNUCKLES to re-align the pinion angle is highly debated. There are plenty of 60s (and I have even seen some 40s with stock springs) runnin' without cut-and-turn of the knuckles. If you don't go HUGE you don't HAVE to do it. Also, with some FJ60's you won't even have to do any driveshaft mods--mostly depending on the years, but most 60's have slip-shafts that are long enough to take the extension of an SOA--but, you may have to notch the tcase crossmember . I have seen a 60 in Moab that had SOA where they just flipped the perches 180 degrees, used the stock springs, ran longer shocks, notched the cross-member and bought a double-steering arm for the steering and it rocked those rocks just fine. Ya, your rig *might* be better if you cut-and-turn, but it might not--personnally I would (and am going to) try it out first without the cut and turn--if I seem to get some crappy vibration, then I'll either go with lower springs (like back to stock springs), cut-and-turn the knuckles, or get an extra custom cv driveshaft. I know some of the 60s have a stock cv joint driveshaft--not sure on the years, and specifics, but somebody else might. One of the most important parts of the SOA is the steering--but there are a whole bunch of ways to do that as well--some kinda sketchy, but most are quite good. As suggested already, read ALL the write-ups on IH8Mud.com (and other websites) about SOAs--even the ones for the 40s help, although, they have more trouble with the driveshafts and pinion angle worries than the 60s do--and make your own choice. Personally, I would love to pay the mucho dinero it takes for a shop to complete an SOA conversion--but that's because it would save me all the work--but I don't have that much. I have some good smart friends that know cruisers and some good smart friends that know alot about alot of other stuff and I am sure we all are going to be able to handle it very competently. And don't worry, you will have people tell you opposite of this and that--that's why you need to do your own research and not just listen to some shmoe and what he thinks about it.
