Very nice project you have there. I like that color very deep looking. I was wondering about the headers that you used. Did you have the do any grinding or cutting to the frmae to get them to fit? I a have a 1965 C-10 and I think that the frame is close to the same dimensions as yours. I seen other people have used Dynatech headers as well just not form that year range. Well thanks for any info that you could pass on to me. Have a good night.
