Ahoy, hoy!

This problem begins due to the empegs odd dimensions. I spent 10+ hours on a handmade mounting kit to get my empeg installed the way I wanted it. Bending aluminum brackets, drilling, bondo, then painting. It was all worth the time it took, once installed, and fitting like a glove.

Then yesterday I drove through a parking lot with thows awesome, gravel camouflaged, speedbumbs. (Going about 30mph) Crack goes my bondo molding...

My Question:
Does anyone know a good online car stereo site with custom mounting designs?

It is for a 1999 Jeep Grand Cherokee.
- It has an "oval" shaped stereo mount.
(If it could help some how, here is a picture of the inside my truck, from ebay.)
- I have already, originally, purchased two different Chrystler/Jeep 84'-03' kits that didn't fit.
