write these 2 axles you have should be single wheel with the diff that will unbolt out of the caseing! if you are bilding one out of the 2 then you need to count the teeth on the crownwheel and also on the pinion, so this will give you the ratio of what it is by divideing the number of teeth on the pinion with the number of teeth on the crownwheel ,ie 37teeth on the crown wheel and 7 on the pinion if this makes sence!
4.62 is ok but 4.44 or 4.1 would be better! also on some crown wheels it is stamped on the edge of the crown wheel!

Hi Madmark
Thanks for the reply, but i was hoping to find out all the info without striping down the dif's.

If its not been stripped down before there should be a tag attatched to one of the studs with the type on it......didnt know that myself til last week, think its Nighthawk you want to thank for that info....could be wrong and cant be ar$ed to look back through my posts...
