Fair enough that you smoothed the cowl vent since it's not needed. I just thought if you were running a heater, you may have plumbed it to collect air from somewhere else. I won't be using the original heater, because a) it's far too big, ugly, and shit, and there's not enough room under the dash anymore because of the firewall recess. So I thought I might smooth the cowl too and plumb the heater somewhere else hidden, maybe a vent in the inner guard. Or I could still utilise it and fit a smaller heater. I intend to do lots of driving with the car, so if I happen to be out in the cold and rain, I'll want a heater so I can see where I'm going!
C notches tend to be very basic, that's the beauty of them, but I'm still interested to see some pics. Do you have some photos of the work you did making the new inner guards etc.
It's not really an easy feat to build a chassis for a unibodied car, nor is it cheap, which is why I'm not going down that road. I don't think it's really necessary either. I will incorporate some strengthening in the car, but ultimately the only major changes underneath will be the front and rear suspension, which are being entirely reworked with 4 link in the back and tubular wishbones and a custom made crossmember up front. There's the firewall recess and tunnel mods too of course. I'm undecided whether I want to fit a cage anymore either.
If I could, mine would be C notched, mini tubbed, fitted with an entirely new floor with greater space in the rear for 4 link, full length bead rolled tunnel and smoothed engine bay with rolled inner guards, but none of that is a practical car building necessity.
The car itself is in such good nick that there's no sense in hacking it all up really, but modifying it to suit.
