You can't give away a gl around here. I need to paint it flat black and put euro bars on it. 
  I'm almost aggravated enough to swap the good parts to the 78. If I did the wheels, that gives the 78 recent wheel bearings, tires, better rotors, I can swap the new pads to match the rotors they are on, swap on the battery, chrome rocker covers, new water pump, chrome intakes, K&N air filter, put the headlight in a 750, and sell the exhaust with the sportster mufflers. I'd probably come out ahead. 
 The 79 does have a  set of 83 carbs with accelerator pumps, I don't want to move those.
