Am looking for a 3.7 or 3.9 ratio H165 diff centre if anyone has one laying around that they would like to offload. Happy to pay freight within Australia and what ever you think is a fair deal for the centre.

i have one, pm me your post code and i can work out a price with postage.

You wouldn't have two would you as I'm also after one a 4.875 ratio? Dan

a 4.8 not sure on that. i would have to have a check.

Thank you

please tell me you have a 3.7:1 h165 centre lying around! I've almost lost hope, and stopped re-advertising a WTB for it.

If you do have a 3.7 gearset, let me know and we can work out a price etc.

I need help working out what ratio it is? i have it out of the diff and there is numbers stamped on the crown wheel i have forgot how to work it out.

Two numbers like 36:9 so 36 divide 9 is 4. So its 4 to 1 ratio, the numbers represent the number of teeth, so you can count teeth if need be on crown wheel and pinion

Thanks now i remember.

The 2 i just pulled out are 4.11 and 3.88 still 2 to go.
