Tootallmike, thanks for the thought. Yes I'm still interested in split drive flanges, perhaps you can drop me an e-mail to Belringer @ ntlworld.com .
I had considered machining some hubs out, but after experimenting I'm not totally convinced that a "real" saving is to be had. It may well lessen steering problems and reduce the noise a little, but is the hassle worth it, when you actually do get stuck !
If like Dr deuce I was doing high milage it might be worth it, but by the time you've fitted bigger tyres, larger engine and an auto box , you might as well have started with a different vehicle in the first place ! I like my jimmy just the way she is,....... Vanilla.
