Folks,

I've got a 1971 dodge monaco with an open differential with (what i believe is a 2.71). I'd like to swap it out for a complete 3.23 suregrip or 3.55. I'd like to still maintain highway speeds of 80 with no problem as I will be towing stuff, so maybe the 3.55 is a bit too high. Where can I go about finding a replacement...remanufacturers? And what part number do I look for? If I remember correctly there were two different types in 1971 and I need to look on the pumpkin to find out?

Thanks in advance...
David
