DANA DIFF CENTRE WANTED

Hey guys, anyone got a Dana 60 diff centre they don't need ? My Dodge AT4 114 has a 4.10:1 (I think that's it), but I'm looking for something around 3.50 or thereabouts to replace it with, at 95K's the 318 is starting to wind up a bit. If someone wants to do a swap that's fine with me as I won't be hauling any heavy loads from here on in, this thing was originally a towtruck hence the diff but it aint too good out on the highway above 90. Please PM me or call 08 84640520 evenings if you can help.
Thanks, Tony - Adelaide
