I'm pretty sure all 1964 864 liteweights had red interiors, while the 1965 990 were the color posted.

You may be right. I keep thinking that after my post earlier. I am trying to confirm one way or the other will post my findings

 

Until then

Here is the Race Hemi pkg componnents

1964 Max Wedge Lightweight Package

In 1964 the light weight was expanded to include more items of a light weight nature to further reduce front end weight on these cars. Below is the list of items as described in a Chrysler letter to Dodge dealers on October 3, 1963. This original letter is included in Darrell Davis's "Complete Guide to the 1964 Dodge Ramcharger and Hemi Charger Package." These parts are listed in the Chrysler letter as:

1. Aluminum hood with air scoop
2. Aluminum front fenders
3. Aluminum front bumper and bumper supports, decals to be affixed to front bumper warning against use of bumper jack
4. Aluminum radiator air shield
5. Aluminum radiator crossbar hood lock vertical support brace
6. No undercoating
7. "Spray-on deadener" will be deleted from entire car
8. Front and rear floor carpets will be without jute backing
9. Dash liners will be omitted
10. Cowl side panel silencer pads will be omitted

This light weight package was not available on the cars equipped with 11 to 1 compression ratio. It is also noted the standard rear axle gear ration with the lightweight package was 4.56 to 1 whereas the 11 to 1 cars came standard with 3.91 to 1 ratio. Although it was not mentioned as a lightweight feature in any of the documents I have found, the steel fan blade used on the clutch fan assembly was replaced with an aluminum bladed fan with a steel hub. I do not have any paperwork that says the Stage III used this aluminum fan before the A-864 Race Hemi engine but it has been suggested by other sources that the stage III was the first. Again if anyone has paperwork that sets the facts in stone I would love to see a copy.

1964 Race Hemi Lightweight Package

When the Race Hemi package cars came out in April of 1964 the package included all of the light weight features that came on the 1964 Max Wedge light weight package. There were also new items added to the above list to further reduce the front end weight of these cars. I do not have a copy of the letter but there was a letter sent to NHRA in March of 1964 detailing the list of additional features added to the Race Hemi cars. They included the following:

1. Light weight thin steel front bumper with aluminum mounting brackets
2. Single headlight grill assembly
3. "Hemi" style larger aluminum hood air scoop
4. Removal of hood hinges, to be replaced with hood pinning posts and hood pins
5. Aluminum doors without arm rest pads and aluminum door hinges
6. "Light weight" bucket seats and aluminum mounting brackets
7. Removal of the entire back seat, to be replaced with additional carpet without jute backing
8. Glass - "Light weight-Corning brand" door and quarter window side glass with quarter window to be affixed in up/closed position. Thin "glass" rear window with special gasket.
9. A larger trunk mounted battery (very heavy), to be placed at the very right rear of the trunk.
10. A special single exhaust system was installed on the 330 two door sedan (post) cars with the muffler mounted side to side just forward of the rear bumper.

The 2 door hardtop is a 426 max wedge car.,,,,,ran beginning of the season.

the 2 door sedan is a 426 Hemi car which came out mid season

That is kind of what I thought might have happened. This team and several others had access to what ever the latest parts the manufactures offered.
