If you are talking about 1970 Chevy 1/2 ton 4x4 Short Fleetside,
9131 1/2 ton 4x4 Trucks produced in 1970, of which 2554 of them were short Fleet. (burbs n panels not included). If you include 3/4 ton, add another 7659 to that overall number. (note no 3/4 4x4 short fleets from factory)..
If you are talking about a GMC, then TCB-1 post is correct, but it would be lower production numbers for GMC..
