I have the exact same truck! Mine has a '68 250 in it and I swapped out the original rear that was blown up for a Dana 70HD out of a '74 C30.

Let me tell you when you get everything sorted out you will quickly find out that truck is TOUGH AS NAILS


1963 Chevy C30 - 292 I6 +.040" 10.78:1, SM465
1978 GMC K2500



"Four gears with a granny low and six cylinders straight in a row."
