HJ60 diff ratios and other nuisance questions

[vando]

Questions for all you 'Yota gurus. How do I tell what diff ratio is fitted to an HJ60? Do they have the ratio somewhere on the data plate, a' la Pajero?
Also, any ideas on what's a fair price for a pair of complete axles, disc to disc, drum to drum?
And is the 2H engine any use to Toyota guys, or are they too old now? Thanks in advance, Andy.
