Possible to get early A down to 2,700lbs?

My 64 Signet weighed in at 2490 something and no fiberglass anything
Wow that is light. I had no idea. Thanks Hotlines

That backlight glass weighs a ton. A 'Cuda will probably not be as good a platform as a Valiant/Dart sedan would. The shoe box is already like 2,700 lbs from the factory with the Slant, but more like 2,900 with the 273.

Can you use a fuel cell? Aluminum stut rods? Aluminum master cylinder? Aluminum differential housing? Aluminum wheels?

Yes I can use all of these. There are very few modifications that I can't do, like swapping to an IRS or moving the firewall. Things like that. There are also tire limitations, depending on weight. The biggest one is engine size. Once you get above 5.1L then the weight jumps up to 3,000lbs and you can run a stroker.
