Timken rear wheel bearing installation
I remember reading too that he does not seem too fond of "most" of these coil over units. I just took a look both though, and granted a quick look-see via my browser is not particularly conclusive, but the XV unit does appear to be more substantial.
One nice thing about these units is that - theoretically at least - you should not have any more alignment problems ... er, that is unless and until they bend ;-) ... the stock unit have inherently poor alignment holding values. I have the Moog kit on mine and that seems to help, but the torsion bar setup is IMO a better design than is the coil over. Indeed the Old Mopar front end is probably one of the most adjustable ever ... for good and for bad.
Me, I don't think I'd ever even be temped to go to one of these replacement front ends unless I could get one for comparable $$$ - that's a ways off I'd say.
As to the ball bearing rears on most new cars ... while I was aware that "some" new cars used them - I was under the impression that was mostly FWD cars. I do know that the orig '64 Mustangs had similar setups, but they too were not the best.
I think the point is that the Green units are prolly fine for the most part ... but for serious handling work I still have to side with Rick on the logic of tapered being superior in design. But as you guys pointed out - and just as I feared - I will probably have difficulty getting someone who can competently install them. So I suppose for now - pending that call to Drivetrain specialists or Randy's ... I'll hang.
