I just got this magazine today. It has a four page spread on the M715. Seems that there were some 1969 unissued M715 trucks. They got one and did a test drive. Hope you enjoy it. In my -20P Parts Book, they show hose clamps on the plug wires. I do not remember them being there when I was in Germany. But I didn't have a 1969 truck. So, maybe that was a later addition. You decide.
