I would like to have the drawings. I like the bracket. It makes the car look cool. Seeing all that mechanical stuff in the back while driving behind it..
But that spare tire bucket is useful too. You can put crap in there for car shows, for example, instead of everything in your hatch area..

Even if we did, I don't see how. They are long-since out of production. If I walk into a dealership and give them the part number, they'll tell me to pound sand. If I walk into a parts store and give them the part number, they'll say the same. So since they cannot be acquired...I don't see the issue in making batches of replicas available for sale, just like any other replica part for a discontinued GM part. Lookin' at you, Corvette Pacifica.

Yes I would purchase one, If a member would have the tools and time they could turn out many brackets as after the set up for one is done the process can be repeated very easily. I gave away my welder a couple of years ago or I would look into it.

Thank You

I am not adverse to making money. GM has a habit of picking on people for making "unlicensed" parts. We all know that. They (GM) sued Mongoose Motorsports here in Ohio for making reproductions of the 1963 Grand Sport. If it anyway says "Corvette" etc and they catch wind, you will most likely get a cease and desist letter.

https://www.autoblog.com/2010/03/22/...e-gs-replicas/

Regardless, I will do the drawings as I want one for myself. If someone wants to setup and build them for money, then it would be nice to be somehow compensated for my time, even if it is just dinner, etc.

The first step is to get pictures of different views, ie: top, side(s) bottom, end etc.

That is pretty condescending, for a while I was a UAW machinist and I could do and did stuff you could only imagine doing. It was a bunch of UAW machinists, welders, etc that were keeping you safe when we were building weaponry. There is a vast difference between skilled workers, which welding is versus line workers loading parts into a press and pushing the button and then taking the parts out.

I worked in one shop that had women working the line. Some of those women had arms so big they could knock you out with one shot. Loading a 1000 heavy parts an hour (means 2000 because it was handled twice) built them up. That didn't take much brains, but if you don't know how to weld, it will either come apart or become brittle.

The key is to get the dimensions correct. Won't do a lick of good if it ends up too long, or much too short, bolt holes/slots in the wrong place.

I was being sarcastic.. I worked with NDT level 3 welders for years. They welded everything from Cast Iron to Titanium, and nuclear containment containers.. Incredible stuff...

My fault. I need that little emoji that states it...
I work with welders, on subs for example. And it takes a long time just to set up. But the quals, etc needing to pass the NAVSEA requirements is very hard. And, they need to fabricate, read prints, drawings.

AAA has one better... 200 miles, you can only use it once a year. That most likely would get my car to MY mechanic, I think the cost of additional miles via AAA aren't that bad

That's a car, though. This is a random part with no text on it whatsoever anyway. It's just a hunk of metal that bolts up to the back of a car. Again, I really don't see how GM would get all up-in-arms if someone decided to make a run of them and sell them.

In any case, I have a bunch of photos of this thing from multiple angles. I threw all the photos I have up in this imgur album: https://imgur.com/a/O0cHSgZ

that will work. I will download them onto my computer and start putting in lines where we need the dimensions at. it could even turn out good enough to not actually need blueprints

When bracket racing my prior '88 I removed the spare and hardware but left the carrier, every 100lbs = .1sec off the 1/4 mile so every bit helps.

My car came with the spare and everything associated with it missing. I got a spare and brackets etc from ebay and put it on. I can understand losing the spare for racing, but for street driving who wants to wait for AAA when you can change the wheel in 5 minutes and be on your way?

That butt dyno... do you get that calibrated every year? I think your mind is playing tricks on you. This is less wight than comparing your car between a full and 1/4 tanks of gas.

Technically speaking, you actually you removed 36lbs of weight from behind the rear tires. Weight that should be putting a downward force and aiding in weight transfer at launch.

However, it is 36lbs and probably affected both traction and acceleration so minimally you can't tell.

Aside from that, I agree with your notions about a spare. Even a lot of new cars are sold without them because of roadside assistance. For a car that is only used on the street and road tripped frequently, I don't get it. For a track car that you are trying to shed all weight possible, I see the advantage if you are removing other items to drop weight as well.
