That kit is heavy, expensive, V-belt, and a big pain in the a$$. Moves your fan forward so it doesn't hit the new V belt, additional pulley bolts onto front of crank pulley, etc... I had the kit and sold it because I wanted to stay serpentine drive, and because it's price went up through the roof so I netted like 5x what I paid for it 2 years prior. I'm adding my A/C compressor onto my existing A2/8.3L serpentine drive via making a bracket to mount it above the alternator and using a universal compressor mount. Re-pin the tensioner spring by 90 degrees to clock it, add a longer belt, and done. If you search, you can find several instances where guys have mounted a second alternator onto the 8.3L serp system, right above the first alternator, which is how I am doing it but with an A/C compressor instead of an alternator. Looks like I should fab up a few extra and sell them complete for $400 plug-and-play? No waiting, no group buys, no thread searching, no adjusting belts or squealing when it is wet, just cash and carry.... You can easily swap out a v belt clutch pulley with a serpentine one, and same with the clutch magnet, or just use a resistor or relay off one battery to drop it to 12V. I would make it for the popular ear mount (not pad mount) type Sanden compressor only, which I think is the one that comes in all the kits most people here are wanting to use. I have not done mine yet, but I do have the parts already to do so, if there are some takers, I may pull it ahead. This would be for the A2/8.3L only, sorry 250 guys, I don't have one to work with in front of me and that one should be easier to source from used truck parts yards. I'd supply required belt length / part number, or could include it for additional pass-through price. Pic below is of dual alternator systems (not mine), of which just put an A/C compressor in place of the top alternator. Also pic of A/C compressor mount type which would be suitable for use with this bracket. Turn-key Sanden compressor model is 4866, which is equipped with an 8 rib serp 24v clutch. Aftermarket version compressor complete with clutch can be had new for less than $200 delivered from eBay. Come get some...
