While going over my newly acquired 1963 SW I found this mystery hole which isn't at Sanders 1963 car. Any thoughts why this is there (FI or airco or something else?)
You're correct, the mystery hole is for the fuel injection air cleaner air inlet. At least two possibilities on the hole. It's possible that this is the original core support and the car was originally an FI car, or the core support may have been replaced at some tine in the cars life.
It's common to see the fuel injection core support in 63-65 cars that were not originally fuel injected. If the support was ever replaced, the service replacement for all 63-65, except those with air conditioning, would have been the F.I. support. It made sense, at least to GM, as one part and part number could be used to service either F.I. or non F.I. cars.
Wonder why the previous owner had the alternator on the left side?
the 63 FI core support differs from the service replacemnt FI core support that mike correctly described.the difference is in the front lower aspect of the orig 63 fi core support's configuration. mike
You have 2 holes in the left hand fender skirt for the Fuel Injection Air Cleaner that I can see in the photo. I believe that your car, unless it was clipped with a used front clip, is an FI car. What is the red line on the tack?
Not sure where the referenced 2 hole are, however if these are the two closest to the top of fender they are for the plastic loops to hold the wiring harness. The FI air cleaner would have 2 holes just above the rubber flap area about 2" above it (as measured from back) and located near the back or the flap area. Then one more hole directly below the rear bolt hole of the double hole area about 3".
I can not see that, however it may be there. You'll know best.
More not worthy is the ALT on the drivers side, FI had it on Pass side.
I might be wrong when I am looking at Rob's picture but I believe that the 2 holes that I mentioned are visible.
Look at the lower left of the picture, about level with the lower part of the alternator. On the skirt you will see a square imprint with 2 holes.
Judging from my observation of the photo I believe it to be higher on the skirt than it looks and it is above the rubber flap of the “A” frames.
The wire harness routing for the alternator does not convince me that the car’s original routing was or was not on the drives side from what I see. There is 2 wire harness’s visually going over the horse collar at the drivers side hinge. Should not there be only one harness strand there?
Again, I may be wrong, but I will wait to hear from Rob and see what he finds.
Tony, YES I can now see the holes. Downloaded picture and cleaned it up a little and there they are! Sorry!
On a 64 the wring harness goes just below the edge of the fender, secured at the two holes seen in the photo then drops down just before the hood hindge, where there is another hole (enhanced picture you can see it) to secure harness to. The wire that is wrapped around the harness is a ground which is secured by the upper left screw (looking at picture) by the hole. The hole also has all 4 screws arond it that are used to hold the FI air cleaner S tube in place, however I do not believe the phillips screws are correct. However, why would one put the other 3 screws around the hole?
From the TIM/JG (3rd) the only option that mounted the Alt on the left was an AC car. Check the Alt number since only 2 were used in 63, the AC Alt was a stand alone pn. In 64 you could not get FI and AC, check to see what limits were on the 63 model.
My comments are strongly based upon my 64FI and 63 was a different animal so take what I say with a grain of salt. I've seen the hole in other 63SWC, but not sure if it was a replacement or not.
On a true '63 FI core support, the "hump" on either side of the rad lower section is common to all '63 cars, so a true 63 FI core support will have the humps also. "64-65 did not. I'm not sure I can make enough from the holes to draw any conclusion, but the presence or absence of a true '63 core support and the redline on the tach would be interesting to see...
My question was actually regarding the big hole with the four screws. Since I'm not into the C2 yet I really have to learn even the basics!
I'm still puzzled since the car has trim code 898E it should be an airco car but I can't find any evidence of it. No duct work, washer bottle holder present. The only thing which indicates airco is the left hand mounted alternator but the wiring does look weird and could be created during a later period (it is running in front of the radiator to cross to the left. I haven't had a chance to study the AIM or check if the front clip is replaced...
The car has a calculated build date of July 2nd 1963 but that doesn't seem late for the used trim code 898E according to Nolan's excellent restoration book.
The car isn't in my garage right now but next time I'll visit the car in its storage area I'll take more pictures of all kind of angles to figure out what is going on here. I'll take a clear shot of the FI attachment holes (if any can be found) and if you could explain where these core support humps exactly can be found I'll take some shots pointing to that area as well!
thanks for all the feedback so far,
Rob.
PS the eBay ad was talking about the tach red area starting at 5300 but this can't be right (unless it is changed) since it either started at 5500 or higher (I don't know the area for fuelies yet). I'll have a look at the tach as well when I will see the car this week).
