Hope someone can point a poor limey in the right direction in sourcing a 44 tooth speedo drive gear.

It's the one which looks like this

Tried suggested links such as http://www.transmissioncenter.net/sp...__va.htm#700r4 gear driven but not in stock
Ideally if someone knows of a company who ships to UK that would be even better.

Part number is ACDelco 25513051 I think

Thanks in advance for any recommendations
