Now, an overview of what I want to do... I want to be able to mount the spare tire carrier on the back of the Ex in such a way that
does not require too much fabrication or cost. I'm sure there are things that people would rather spend money on than this, and if we could all afford to we'd just buy the bumper mounted ones and away we go. Now, I just picked up a welder, so I have yet to actually learn to use it, so any welding there
may be will be minimal. Also, I'm a student and work part time, so I won't be paying a shop to mount this for me. Finally, I'm going to try to mount this so that it can fit a 33" without flexing the body when open, while retaining a mostly stock appearance.
Now... for the fun stuff... the brackets appear to be one piece aluminum or steel... the tubing for the carrier itself is squared off at the end with a hole drilled vertically through it... the tubing sits between two "tabs" on the bracket... these tabs have holes drilled in them, and everything is secured with a bolt with one of those lock washers (or whatever they're called). Now, I can choose to keep the stock brackets and modify them to work with the body, or I can replace them. At the moment, I'm doubting that modifying the brackets would be easy, so I think I'm just going to remove them and make my own.
Also, maybe I'm taking the easy way out on this, but I'm mounting the carrier so that the bottom of it almost touches the bumper itself... This will allow me to mount it low enough to clear the side window and the taillight. Normally this wouldn't allow anything to me mounted to the carrier, negating the point of having one, but I'm going to mount it so that the "outside" of the tubing sits level or just behind the back of the bumper... that means that the tire will sit behind the bumper, rather than over it. Not only will this give me virtually no limit on tire size, but it'll also give me more clearance between the carrier and the hatch, in case I want to add a hi-lift jack or whatnot there in the future.
Sorry for the super long post, but that's the rundown on the carrier... This is only the introduction though...

I'm one of those people that likes to know all the details of what I'm doing, so if this gets mounted expect a long write-up... I'll be asking a lot of questions and posting a lot of findings.
Thanks to everyone that has commented and helped out so far... If it wasn't for that support, I probably wouldn't have gotten this far...
