My son bought a 1959 Chevy 2 ton C 60 this summer. It has a
283 and a 5 speed transmission.
I went on the GM Heritage Center and found that the frame
width on the front of the frame for a 1959 3100 - 6600 to be 34"
The same dimension for the 1951 3100 - 6500 is 35"
It is raining now and will not have a chance to measure but
I will find out the distance between the 59 steering gear box/column
clearance tomorrow. Though there appears to be a lot of room
on the 59 2 ton. Jeffrey
