  1. The script for the metal cars is different from the Avanti. The originals came out in 1956 and had rectangular mounting pins, and special barrel nuts that no other company supplied. Avant scripts have round mounting pins. I have seen flat spring steel push nuts on the pins, and also some with acorn tinerman nuts.

  2. The top jamb nut and screw have NO correlation to throttle pressure. That is crazy controlled by the overall length of the pressure rod to the transmission lever. That is adjusted by a threaded clevis from under the car. The lever should connect inboard of where the foot linkage hooks up to the main linkage. The correct way to adjust it is to remove a pressure port plug on the transmission, and put a gauge to read the pressure. It should be 75 lbs at fast idle in gear. Adjust the length of the rod until it is in spec. Nothing else is correct, and it is just guessing.

  3. The ORIGINAL and EARLY McCulloch superchargers had a bakelite clutch under the races. They were not pinned or fastened in any way, and would slip (on purpose) when boost exceeded the set solenoid regulator pressure. This slipped the outer races to the same RPM as the input shaft and ball driver, thereby stopping the balls and any slippage and resulting heat and galling. By the time they went to V8 models, and higher RPMs then they pinned the races as the clutches would burn at the higher RPM.

  4. Your year Avanti uses the same bendix calipers as the original Studebaker Avanti. NOT the ones listed in Rock Auto. Sorry, they are about $200, not $40. The little button on the piston is there for pad retraction, There is a pin inside the caliper, and there is a friction clutch inside the caliper piston, There is a spring that pulls the piston back a pre-determined amount every time you release the brake pedal.That in turn pulls back the pad, via the button that the pad slides over. It will still work ok, without the pad sliding over the button, but it would be better if you had it. The only thing may be a little bit more squealing, and some slightly increased pad wear. 

  5. Excellent quality. Fit on one end was slightly off, but it may have been the slight damage to the outer end I re-used. Much better than the later Avanti II bumpers with the crease across the length of the top. Much better than most rechrome shops. I have had peeling on the back sides, marks where they straighten on the back side, and waves, and grind marks that were unacceptable on rechromed units. None of that is true with the new ones. You will have to find the large cage nuts and use them on the new.
