Its a bit like granddad axe.....
I got HB7405 late 79 and it was a 1600 Super with Rect headlights and Metallic SilverBlue (Mistral), after the 80 Daybreaker damage it was rebuilt as a Chrysler JS8201 and painted white with brown strips then at the end of the season I rolled it and then repainted it white with a blue side strip which it stayed until I did a major tidy up in 86, still white but with Talbot Sport colours red, dark blue, light blue and yellow strips and this is how it was when Trevor Weir bought it off me. I think it stayed this way while Trevor had it, he sold it and its next owner reshelled with the 4 headlight Alpine shell and it later returned to the Weirs and this is the shell that you have.
Re the breather pipe, yes I still want it and I have a GLS rear quarter panel moulding for you
