Does anyone have or know where I can find Detailed Gearbox and transfer case specs relating to gear ratios and when they were manufactured and what countries they ended up in ?

I'm wanting to know the ratios for my H55F and transfer case in a 85 aus spec middy with a carby 3F and what other H55F/A440 transfercase ratios there are. I've found two low ratios 1.959, and 2.488 but not sure what cars had what and if i've already got the 2.488 ratio low range

cheers
