OK - thanks (I was actually hoping for less expensive than the eBay guy lol)! I think I am leaning towards the frame rails where I can just drill and use a self tapping screw. In the fenderwell is kind of neat, but I don't want to have to weld and that could be a pain if you need to get to them...
I actually just finished painting the engine bay last night the best I could with everything masked off, much better! I will post some pics today
