I bought the 1/2" spacers from home depot, about 89 cents a pack which comes with 2, then measured and marked the 1/3" line on them. Took a dremel with a cutting wheel and cut them down to size.
And here's a top view of the speaker with spacers installed
Now I know some audio expert people are probably going to chime in and say that there's a problem with my setup and that is that there's a gap between the speaker and mount. Yes for proper channeling of the speakers bass, this is a bad thing. I have yet come up with a way to enclose the area as there are no 1/3" thick ring spacers available that I know of and I haven't gotten around to making my own yet. I tried out a baffle today made by Boom Mat and was really unhappy with it and the baffle completely encloses the speaker and when I did a test run on the first speaker I installed one to, I lost almost all bass to that speaker. So I advise against anything that completely encloses the back of the speaker.
Alright, this concludes my DIY for now. I hope these helps everyone that is looking into doing up their own speaker system and answers a lot of questions you may have.
Please if you have any questions about anything dealing with the installs, feel free to ask me or post in or make a new thread in the audio section and everyone that has done a swap will do their best to answer your questions.
Also, for those of you with regular cabs and/or alpine systems, if you would like to add to this DIY please contact me and give me all the needed info/ pictures. I'd like to make this DIY as helpful as possible and I cannot do that without your help since there are different cabs and oem setups. Things I'd really like to add are center dash speaker, headliner speakers (if anyone has done them), and the rear speakers in a regular cab.
So please enjoy, I hope this helps, and let me know if theres any corrections I need to make and what I need to add.
Also, if you are also wanting to swap in a new head unit, I'd like to refer you to a DIY by 0212353 (JJ)...

I agreed with most of your write-up, until this front speaker setup...
Yikes! This is real bad, not only for sound quality that must be horrible but also for the life of these poor drivers, that will not be very long.
What you need is this:

They come in different depth from 1/8" to 1 inch. Many companies produce MDF spacers, but you can even do them yourself.
The proper way to do it, when you remove the door panels, is to mount the spacer alone, cover the door panel (inside of exterior and around the spacer going under the inside door panel, with Dynamat. Then, remove the screws and install the speaker. I am not saying that sound is not going to come from your setup, but since the driver has obviously no back pressure, it can't be sounding better than the original.
