Data indicates that there were cars with color pinch welts and cars with black pinch welt.

            1963 models, after approximately VIN 5,000 and 1964 models until approximately VIN 15,000 have a notch cut in the bottom of the hardtop to give greater clearance above the door. For Judging purposes, those models can be identified by the raised areas in the outer door panel where the door handle is attached. A redesigned outer door panel was introduced in 1964 at approximately VIN 15,000 which eliminates the interference problem with the hardtop. Models with door that do not have the raised area at the door handle should not have a notch in the hardtop.  

The Auxiliary Hardtop for 1963-1964 models had three distinct designs.

Design One: At the startup of 1963 production the auxiliary hardtop had a notch cut in the bottom, each side, to give greater clearance above the door. This design was present until approximately March 1963.

Design Two: For cars built in approximately April, May and June 1963 the notch in the auxiliary hardtop is not present.

Design Three: For cars built approximately near the end of June 1963 until the end of 1963 production and all 1964 production the notch in the auxiliary hardtop is not present and rear window reinforcing brackets are present at the upper center and lower center of the rear Plexiglas.

Says that from August 1963 throughout the 1964 model year a circle surrounded the 307 13#. 

I have no such circle.

Claims that the square 90 degree connector is typically stamped with "GM" in multiple locations.

Mine is stamped "P" in only one location.  My 1963 unit (purchased in 1972) has the same "P".  Talked to a person who's into FI restoration work and he said it's a "P".  If you desire I can make a trip to a friends house to look at his bigdog house unit - since his car has not moved since the mid 70's and he never had any interest in restoration.

I have also pointed out that the fitting on the 64/65 FI doghouse that connects to the front oil breather does have a "P" on it - where the TI&JG calls for only GM marks. At an NCRS Northeast Chapter tech session on Sat (4/8) and talked to member who tracks 64/65 FI units. When I asked the question - he said its a P without even thinking about it.

Manual states that part numbers and logo's are not on the cover or housing. A search has shown that multiple people have found that the logo, oval with MFG inside it, and part number 19154 housing and 19156 cover do exist.

"Paper shield is attached to one of the flasher's terminals."

Referring to "The rear spring is painted semi-gloss light gray" implies that the spring is completely painted.

 This paint was very tough and still adheres close to as originally applied. In the two 1964 9-leaf springs I've taken apart, the paint is primarily on only one side, toward the center, and only slopped over the sides. Suggest that "partially painted" be added.
