Default Question for marty or anyoen that wants to give some input

I want to cut the inside of my inner fenders, here is a pic of what i'm talking about, but i plan to cut off more like the hinge area, all the way up to were it bolts ontop of the cowl panel. I think it shoudl be fine since i will be having hood hinges mounted on the roll cage bars.

If you cut it all the way to the top of the cowl panel, what's gonna hold the fender on?

it will still be bolted y the door and on top of the cowl pnale. so really the only hole its gonna lose is that one on the firewall.

The problem if you cut that is the fender going buckle. That the main strength in the fender. Unless you are planning on bracing it somehow.

most of it main brace should be there. i'm only cutting the stuff you can see. I wanted to take all of it out, but figured it might get weak. i was planning on running fiberglass, so i figured metal ones would be better. I was about to cut too, but i said i better see if anyone posted

You might wanna go with some lighter hinges now. The ones that don't accept springs. Like on modern vehicles with hood props. Those stock TA hinges are heavy too.

Just make sure you have a strut brace from the front of the frame, to the cowl.
That'll take care of the front to back flex, but will do nothing for side to side twist.
For that.. you'll need another brace between the two in front of the motor.
kinda like a LeMans bar on the old Mustangs.

As far as the stock hinges... toss or sell them because you can no longer use them.
You can make a very simple hinge arrangement at the rear tops of the fenders.
If you're using a steel hood.
get a 1-2" hole saw bit, and drill the inner structure every 3"
Couple of more pounds there

Don't feel alone Dave.
This is the exact same stuff I'm doing to my Chevelle.
With the motor set back, different suspension, etc. I'm hoping to be shaving about 2-300 pounds off the front.
With a 6-700 hp motor... that will hopefully give me a better power to weight ratio, and almost zero front to rear weight split.
