Build sheet 63 Avanti

[Gunslinger]

I believe it was around 1968 that three-point lap belt/shoulder straps began to be required for hardtops, sedans and coupes and around March 1969 when they became required for convertible cars.

I remember my Dad had a 1970 Lincoln that had the three point system...a lap belt with a shoulder strap that was retained at the roof line and connected to the lap belt. The three point inertia system we know came about a few years later.

Our 69 LTD hardtop had such a system.
I think my mom's 73 Mark IV did as well, but my 74 Mustang II had the built-in 3 point inertia system.

My 1982 Mazda 626 sedan had a track system and when you started the car the lap/shoulder belt would travel from the windshield area back to the door post area. Engaging the seat belt took care of both safety features. The front passenger side malfunctioned and I ignored it until I started having a passenger in the front seat. For safety reasons I had it repaired and it was quite costly for something that should not have failed. I bought the car privately as I always did for a work car and transferred an extended non-factory warranty. I would not do that again. I had a transaxle fail and they insisted on putting on a rebuilt unit the insurer provided which caused major problems until I identified a person at the dealership who could make a decision. We pay for our educations. That car was one of the best cars I ever owned as it was comfortable and performed well.

Sorry I am so far off subject, but maybe I am not!

Does anyone know what X84 stands for? I have that on a build sheet for my 1963 Avanti also.

IIRC, rear seatbelts. The X indicates the item was included at delivery for dealer install.
