Hello everyone, I have been browsing Mazdaroadster for quite a while now, but for the first time, I have a noobie question to which I found no answer, so I am registered!

I drive a 90 miata. I'm thinking about changing my side mirrors, because both are old and crummy, and last year I had to glue them in place because, well, they're just done with. I could potentially repair them at a low cost, but I'm thinking all the hassle may not be worth it. There are a few things that are on my mind right now.

I want to know if I can replace my mirrors with mirrors not-so-intended to be on the miata NA. For example, if the pattern dimensions are not the same, how can I get around this? Can I simply cover the old holes up with bondo or something of the likes and make new ones? Or could that cause problems? I'd really like to not have to go through that kind of hassle, but there are some very cool much cheaper mirrors than the ones "made" to fit in the miata door socket.

I am a big fan of these mirrors, but like I said, not sure about the pattern and such: http://www.ebay.com/itm/Datsun-240Z-...-/221422517248


I also want to know if there is a no-no in terms of how long the mirror arm is, will it cause adjustment problems, or maybe even be too wide, (also, even though these say they fit the miata, I'm not sure 100% because you get no measurements, just pictures) because my second option so far is: http://www.ebay.com/itm/F3-style-ABS...-/281318529773

If anyone can vouch for any of these mirrors if you have them, it would be greatly appreciated as well.

Thanks in advance
