Initially the fan was striking the calrod supports, had to put a little duct tape on end of a long skinny screwdriver and gently massage blades back into position. Heater ran well every day since the repair for the last week and was able to heat my uninsulated, rafter exposed car and a half block garage by twenty five degrees in less than three hours. 25F to 50F one day and 40F to 65F another day. Once I insulate the ceiling I can see it getting pretty comfy in there and hopefully the heater will shut off on its own and save me 0.50 cents and hour.
