What makes you think it's a later 235? No vent slots in valve cover? I can't see the water pump to tell if it's high or low. What about 12 volts? I think I can see a black, greasy generator. Is that a balast resistor on the firewall?
I agree with the others that it's a 54 - with a 2-piece windshield - for some unknown reason. Cool old truck! Congrats. I hope you can get it running and back on the road. Good luck.
