I am looking at buying a Dana 60 out of a 1965 ford truck to use as the basis of a rearend I am building to replace the 8 3/4 in my car.

My question Is would this rearend likely have a power lok as it is an early pre 1969 rearend, or did danas not change with the years like our 8 3/4's did? Is their an easy way to identify what style of posi is in this beast? Also I understand that the power lok is a clutch type "posi" unit. Does this mean the trac lok is a cone style unit?

I've briefly searched google and the tech archives here and I can't seem to find all the answers I am looking for so I am turning to you guys.

Thanks in advance,
Dustin
