Eric,
Check out the pics in the link below my name. I have a 1947.1 GMC COE EF-302 model. So far I have rewired her, swapped for an sm420 transmission, rebuilt the driveline and rear axle, all new brakes and brake lines, rebuilt the hydrovac, rebuilt the front axle and steering box/column, cleaned and resealed the gas tank, new fuel lines and much, much more.
Pretty much rebuilt everything needed to drive her down the road with the exception of tires. The engine hasn't had much more than a good cleaning although I did modify and add an HEI from a 292.
Finding a 236 is fun. They aren't really all that common.
Take care, Jeff
