Early Avanti’s had insulation covering the underside of the front half of the hood due to a hood cross-brace. Partway through the production run the brace was dispensed with and insulation covering nearly the entire under hood area was used.
Avanti Motors began using the push-type wiper/washer switch at RQB1563 during the 1970 model year. Prior to that it looks like the Studebaker foot pump washer was still used.
A ‘69 would use the red Studebaker vinyl bag as the washer reservoir mounted on a bracket on the passenger side inner fender apron. The washer pump would be mounted on the top of the bag.
The washer switch could be located in one of two places…depending on when the car was actually built. It could be a foot operated switch by the left foot…the Studebaker type…or it could be combined with the washer switch which would be pushed in to activate it. I don’t know when Avanti Motors made the change from one to the other.
Look into the Turner kit…you can get it from Jim Turner himself or Jon Myer at Myer’s Studebaker. It contains all the parts necessary to convert to Ford rotor and GM calipers and pads plus bearings, hoses and other parts. It’s the way to go.
I believe early Avanti II literature stated the Stingray engine…they never said “Corvette”…put out “nearly” 100 horsepower more than the original Avanti. A bit of hyperbole but hey…that’s advertising.
I’d say Prestolite…ignition points, condenser, cap and distributor…starter…alternator. The only big thing they didn’t provide was the spark plugs…Champions were used…kinda surprising as the rest was Prestolite…or Prest-O-Lite as it was then known.
