damn you have way to many worries boy. I talked to someone at out local arctic trucks. and he told me that your truck has 7,5" front = same as the older models and 8" rear = same as the older models...
I donīt know about your gears but you could raise one wheel and count how many turns your drive shaft takes against how many the wheel does.
You already know you have the r151 trans and behind that probably sits a normal chain driven t-case... or it has the old turbo t-case with 23-splines.
there is some info on the main page of marlin crawler about how to Id your t-case. I would look that one up. I was suggesting that you contact arctic in norway because I know the have all the info for your truck and I know that you speek finish you should be able to figure out the norwegian....
But if you whant top quality part that you can relhy on I would suggest directing your busshness to marlin.
But you should realise that diffs arenīt stronger than the person that sets them up.
about the locker. I basicly have no idea what you are talking about I would just look it up after the 8" or 7,5" category.....
I hope that you find some of that info helpfull. And I wish you best of luck with your truck.
with regards Bassi
