[FHC1971]

My 1971 Firebird Formula came with Deluxe Belts (AK1) option. The shoulder belts are missing. Does anyone know the model # for Hamill Belts that my car should have had from factory. Also, if it makes a difference, my car came from Van Nuys.
Thanks Frank

There's various model and part numbers in the Part Manuals, the 67-75 not as easy to look through as separated volumes and no search option for digital version, mine anyway. The part number on the belt may not always match the part number GM listed either, if you were simply going to search through belts for something that matched. Or it might.
If I get a chance I'll have a look, front shoulder belts, not the rear option.

Thanks. Yes front. It might be easier if someone with a 71 Firebird with Deluxe belts just looked at their belts to see what they have. I believe the regular belt made by Irvin is model 2050.

Will look at early '70's seatbelt stock, have parted quite a few '71 Esprits.

The 4 digit model number will be the same between the front female belt & the male shoulder belt. Just went through this on my '72 belts (having tags made). Are you missing the female belt as well as the male shoulder strap?

[FHC1971]

The important end is the male. The female end can be different. Length is very important for the male (shoulder) end. The elastic makes the length critical for the male end.

interesting discussion;
I don't know anything about "Hamill" or "Irving" (I will have to look into what this is)...

I had understood that the 70-72.5 (male) shoulder belts were all the same parts (belt color not withstanding);
I had understood that the female side was the same part between the lap and shoulder belts - and the variations were black plastic housings (with black belts; standard) and either colored plastic housings (and color matched belts; deluxe) or brushed stainless stainless housings (and color matched belts; deluxe).

I did not know the model number was for the pair;
I have interpreted this as meaning the match pair had corresponding model numbers on the tags.

Hamill and Irvin (not Irving) were the suppliers

that makes sense;
iirc my tags are all quite faded.

Here’s the tags that are from my low mileage original interior. 71 TA. Shoulder belts had two tags. One close to the point where they are anchored to the roof and the second by the buckle.
