definatly the same as 89 - 91 bighorn and all Mus except the gen 3 which you wont find at the wreckers yet. Possibly the same as the 92 onwards bighorn but not sure. Whats wrong with yours?

leaking fluid from high to low mark every 600km or so i brought the truck for $700 after it had been sitting around for 18 months before that it had been used to get the cows in on a dairy farm i figure the bottom seals gone and the shafts rusty thought i would get a spare put it on and do up the original if its worth it good night job for the winter cheers john
Normal place to leak is the top input seal. There is a Faq foe this on the faq page but if the shafts rusty it might be better to replace. I had my shaft remetaled 5 years ago and its fine and the bank account has nearly recovered

Mine started leaking recently and got a good secondhand one for $100. An hour to put it in and all is well. Would not bother paying $400-800 for a fully recond one in a 20 year old truck when plenty of good spares about at these prices.
If you buy a second hand one Its worth doing the top seal before putting it in and also check for freeplay and bindind across the whole movements. 20 years and 200000km is very close to the life expectancy of a steering box
