I hope I don't disappoint. Now the cab is brass, but true to the real truck, Im building a fiberglass hood. The first one I made unfortunately didn't work out so well, but I'll show you the pictures of the forms I used.
I used copper tubing to build the general shape.
I then covered it with masking tape and taped the styrofoam fender blanks to it.
I then covered the whole thing again
and this is how it fit to the cab, but the fenders are to low, unfortunately, I didn't notice till after I laid the glass(sorry I don't have pictures of the glass hood) so I have to start again
