Gus asked me about the following items from the 3rd edition of the 63-64 JG. Page 88, section 5, L84 fuel injection air cleaner.
#1 Air cleaner mounting reinforcement plate on back side of wheelwell.
"THE PLATE IS INSTALLED PRIOR TO WHEELWELL UNDERCOATING AND THEREFORE HAS EVIDENCE OF UNDERCOATING ON THE EXPOSED SURFACE".
I thought that the reinforcement was added later, after wheelwell undercoat.
#2 Screws that fasten the "S" tube to the core support.
"A KNOWN ORIGINAL HEADMARK OF THE EARLY TYPE SCREW IS "M". AFTER APPROXIMATELY 1963 VIN 9000, A BLACK PHOSPHATE HI-HAT RECESSED HEX-HEAD SHEET METAL SCREW IS USED".
I thought all 63's and early 64's used a 5/16" hex head screw with an "L" headmark. I thought the high-hat 1/4" screw didn't appear until early in the 64 run.
#3 Location of the three air cleaner clamps that secure the rear elbow to the main canister.
"THE CORRECT LOCATION FOR THE UPPER-MOST CLIP IN EARLY TO MID 63 MODELS IS ABOVE THE REINFORCEMENT BRACKET. IN MID TO LATE 63, THE CLIPS WERE ROTATED AND THE UPPERMOST CLIP WAS MOUNTED BESIDE THE REINFORCING BRACKET, CLOSER TO THE INNER FENDER SKIRT". oVERLAP IS POSSIBLE HERE, WITH MID TO LATE 63 AND EARLY 64 MODELS SHOWING EITHER STYLE OF CLIP LOCATION".
I thought the order was reverse, with the clip moving to the reinforcement bracket in mid 63, not off of the bracket. I also thought that the 1st design air cleaner was replaced in production because of interference with the choke hot air tube and at some point, all 1st design air cleaners were replaced with 2nd design so it's would be highly unlikely to see a 1st design on a late 63 and especially on a 64.
#4 Air cleaner finish. (paint)
"THE ENTIRE ASSEMBLY WAS PAINTED GLOSS BLACK".
I thought the main can of the air cleaner was painted gloss black but the "S" tube was dip painted in semi gloss black.

Any input/info/documentation appreciated.
It's possible that these items have been changed/corrected in the 4th edition so disregard if this is the case.
