Masnaka this is what I use behind the radiator-infront of the engine. Allows you to place EFI fuel presure regulator, remote oile filter, remote hook ups- etc. easy to get to without geting under the car and is relly impressive when everything is hooked up.
Huckelberry5 this is a picture of the new CRII mounting holes for the seat belts-two on each side of the car for the lap belts. In your case you will simiply drill a 1/2" hole all the way through the frame, then using an appropriate lenght bolt (very critical- they can't be too long, mount the seat belts after the body is on and make sure by using washers or spacers there is no gaps between the frame and the fiberglass.
