GB, I've heard the term used for both items mentioned for so long that I've just gotten used to it meaning 'either or'.
I put a '76 Camaro front suspension under my '56 F-100 and to many/most, that's a front clip.
I also like the looks of your shop and admire the projects that you undertake. I have a '57 fridge waiting in the wings for my attention so am partial to yours.
