thanks.

I plan to build a stock mount on my own. any help would be great

 

Spearco. They are over in Van Nuys, so it's relatively close. If you do go there let me know so I can see your car

 

they usually use bar and plate cores from spearco or similar. I've heard recently that tub and fin are even better for SMIC -- which the rule I always had heard was tub & fin for FMIC and bar & blate for SMIC. I haven't had the time to investigate on the net, but I'm sure if you went looking you could find some real research from some hard core tech guys.
