70 duster: updating, and a no-dough pro-touring makeover

yeah, im trying to get better with actually USING spellcheck on my posts. this time something happened, and it got awfully funky. ive been far too lazy to go back and edit, and dont have much time to between work and the holidays.

i agree on the electrical connections being dirty. also may be a bad blower switch in the dash. seen them where they go bad an heavily limit the amount of voltage and amperage they pass through to the motor.
