So my 2002 Xterra.

I've put an aiwa mp32cd stereo in the stock metal mounting brackets and then the front assembly thing that should go over the stereo (the big piece that has the 12v outlet and covers the vents, and makes the fron interior overall nice) won;t snap all the way back as it should. i think the stereo is just a little too wide in the front. so now i drilled holes in the mounting bracket so i could mount the stereo a little further back in the brackets and the big front plastic piece that holds the 12v outlet and covers the vents, etc now fits in well, but it's bent and uneven and i'd just like to get the two new metal brackets and start over.

is it normal to have to drill holes in brackets to make stereos fit in certain cars and where can i get new brackets or ones with holes in the right place for my stereo.

thanks for any help/insight, etc...
