Re: WTB front diff
Was just gonna advise you of the one for sale but I see turnerpike already has :tup:
WA to CO should not break the bank either. Have the seller place it in a plastic storage container ($7-10 at WalMart), tape it shut and send it FedEx ground (est $75). Been there....done that. Works fine.
Also, Greyhound now ships items in their buses if room permits and their rates are super reasonable. Might want to check with them as well.
