Inner fender wells

Imagine kind of upside down L. The long leg of the L will butt up against the firewall and the end of the short leg will butt up against the top side of the frame rail. In your case, the top of the stock shock tower will attach to the "snout" bar as well, to reinforce the top of the shock mount. You have to keep in mind that the engine compartment aprons act as an integral part of the car body's "frame". Since these cars don't have a separate frame like the GM cars, for instance, all of thse panels are there to support the structure of the car. When you remove these panels, you will typically need to replace their strengthening properties in another manner. The tubes talked about here are typically found on drag cars with greater than 6-point roll cages. You have probably seen them, they generally go through the firewall and then tie into an upright that kinda follows the A-pillar. Hope this helps. L8r
