Is the rear end from the newer trucks approximately the same width so they fit the 67-72 trucks? Post some pics up of your swap. Thanks

The initial post by grease monkey states he is going to use a 2003 rearend. Therefore can any 1999 and up rearend be used with modification in the 1967-1972 trucks. Are the track widths approximately the same?

from what I can find, the 03 rear track width was at 66 inches.
The 64-69 trucks lists the rear track at 60.5

Found a list on the crankshaftcoalition, i just lost the link but you can google it.
