I have the topper that my father-in-law had on the 73 El Camino.
I have no use for it and would like to see it go to someone that would get some use out of it.
Mine is a 73 and I am certain that the bocy style is exactly the same thru the 77 models, so it will fit all 5 years.
It would have to be picked up. I am about 25 miles off the Saginaw Bay, in Michigan.
E-Mail me if you are interested, or post a note here and I will check in from time to time.
Thanks
