I have one NOS spacesaver spare, the canister, and the mounting bracket that holds it to the wheel and J bolt. They are not for sale since I only have one and as I'm sure everyone has realized, they are very hard to find. I'm saving the setup for a future restoration. It does look very similar to the picture posted of the 79 Z/28 setup. I'd have to look at it to see what size and brand it is but I'm thinking it's a Firestone D70-14 but can't swear to that. A D5DZ inflation canister just sold on eBay for 80-some dollars I think.
I've had several 77's (mavs and comets) and all of them have had the full sized spare, the space saver must be really hard to find.
