  1. P205/75R15 would be closer to the original size 670-15.  P215/70R15 would be about the same height and circumference but if your Daytona wheels are 6" wide would be fine.  

    Getting down to practicality...if you're experiencing no issues with tire clearance the P215/75R15 is fine.  The slightly larger tires will cause some speedometer/odometer inaccuracy but the Avanti has never been known for being accurate in that regard.  

  2. What I found out some years back is that parts manufacturers have consolidated parts numbers rather than stock specific parts for specific cars.  Just because a parts fits physically doesn't mean it's correct.  I found that out on the '70 Avanti and '69 Corvette I owned.  Parts books showed the rear wheel cylinders for the Avanti were the same as the front cylinders for certain Jeeps...wrong!  While the Jeep wheel cylinder looked and fit the same they had a bigger bore diameter and the rear brakes locked up immediately from the added fluid pressure.  

    You have two options...get an adjustable brake proportioning valve and experiment to find the right front/rear pressure or go to Myers Studebaker or Dan Booth at Nostalgic Motors and order correct wheel cylinders.  That will be a bit more expensive but it will also fix your problem without experimentation.  

  3. About all I can add regarding the 2002 Avanti I owned is somewhat conflicting.  Avanti Motors told me it was the 20th new series Avanti built but the paperwork I received from John Hull said it was the 22nd.  The only thing I can make from that was it was the 22nd car ordered but the 20th actually completed and shipped.  The company told me it was the red car used in some of the advertisements but them saying that doesn't necessarily make it so.  

    Some of the early cars showed differences in detail.  At least one had blacked out Avanti emblems...mine had chromed.  At least one had headlight buckets painted body color...mine were blacked out.  At least one had backup lights in the trunk lid like the original Avanti...mine had backup lights in the rear bumper.  It seems they were trying out different design treatments before settling on a standard on the early cars.  

  4. If not already done...replace the radiator hoses...particularly the lower hose.  If it's collapsing under vacuum pressure when driving it will cut off the coolant's circulation.  Test the radiator cap...if it's not hold pressure it will allow coolant to boil over.  Make sure it's the correct cap...depending on whether the car has a closed or open system.  After enough time it could have been changed from factory.  Also make sure the radiator holds pressure.  

    After so much time has passed any car can have cooling issues.  

  5. My '70 had two steel engine mounts.  The only reasons I can think of for the two dissimilar mounts are one has been replaced or Avanti Motors had a new batch made of alloy and yours received one of each in assembly.  Never say never with Avanti Motors...parts were not always pulled in any kind of order and could easily have had two pulled of non-matching metals.  

  6. You might want to replace the rubber brake hoses…especially if you don’t know how old they are.  They can look ok externally but internally go bad.  
     

    By any chance…did the brake fluid get replaced by silicone DOT 5…or already had DOT 5 replaced by DOT 3 or have them mixed?  They’re not compatible and will make the fluid turn into a milky looking mess that will give a very spongy pedal if not fail altogether.  If that occurred a complete flushing of the brake system is required along with new hoses and seals.  
     

    DOT 5 also requires a thorough bleeding of air.  Any bubbles are much smaller and can be a bear to get rid of.

  7. Vintage Air does make quality products.  There might be another possibility…one of the vendors…either in Avanti Magazine or the SDC’s Turning Wheels makes a bracket for the Sanden compressor.  It might be just for the Studebaker engine…not sure.  You might also check a source like Summit Racing to see if a Sanden compressor bracket is already produced for the Chebbie engine.

  8. The door may have been reupholstered at some point...covering where the switch goes...or the adjustment switch could have been located elsewhere such as under the dash.  Maybe the wiring is for something else someone might have installed?  Maybe the wiring harness included those wires regardless of whether it was to be equipped with power mirrors?  

    The best way to find out whether the car was factory equipped with power adjustable outside mirrors is to get a copy of the build sheet from Nostalgia Motors...it will show how the car was originally equipped.
