They say 1982 and 84!!!
Today took the generator/fan assembly to Don's and we disassembled and cleaned up all the parts, Don is painting the parts, I had to leave to purchase a new bearing to replace the old bearing that required grease/oil. Not any wear problem yet but was dry, replaced with a sealed type bearing.
Also, started to pick at the intake right below the weld patch with a straight screw driver, opened up a hole about a 1/8" x 1/2" long. The intake alumiun was as thin as an egg shell. Looked at another intake Don had that was weathered and it already had a hole corroded in the same spot as the location on the 34 intake. Took intake to welder friend of mine and he is going to close, will continue to look for a better 34 intake, Bruce
