The Duster Missle in Big's museum has a strut front end installed by Ben Donhoff in the early '80s as it was wrecked when he bought it. As Stewart P posted above, it's all changed from the firewall forward. Donhoff said it was easier to put a strut front it it than to put it back original. Besides, he just wanted to race it and at the time didn't care much if it was original.
