Did chevy make a 1964 dually pickup?
Chevrolet did make a 1964 dually, the C-30. It sounds like you have a “built” pickup. Most Chevrolet half-ton two-wheel drive pickups of that era had 6-lug wheels and axles with coil spring rear suspension. As you said a GMC 2500 looks close, I assume it’s an 8-lug rear end mounted to leaf springs. As you stated it’s a dually and the VIN is for a C-10, the first idea that comes to mind is it’s a 1964 C-10 cab and front sheet metal mounted on a different frame. This thought is mainly because C-10’s of that era had control arms and rear coil springs. It wouldn’t make much sense to mount a dually axle to the coil spring setup. With this premise… It could also be 1972 or earlier frame. If it’s a 1972 or earlier frame, then you’ll probably have a Eaton type rear end. These were installed in 3/4 and 1-ton trucks and have circular shaped rear differential covers. Parts for these rear ends are a little difficult to find. You’ll just have to search wrecking yards, swap meets and NOS parts sup
