i also would say front and scrape up the other 230 for aussie or 280 for lock right (p.s. the aussie is the same thing as a lockright and cheaper). why put the arb in the rear, then you have to come up with enough for an arb before you're locked front and rear. if you only have one selectable locker, you want it up front (steering issues). it's not that hard to come up with 250 bucks, so you'd only be locked in the front for a few months before you're locked all the way around.
my 68 has arb front and nothing rear for the moment...course, i still haven't gotten around to mounting the york to air it up yet either, but it's a land cruiser, so it will go more places open than most vehicles
