Thanks Cletis.
I did a quick web search for that part number and it comes up as 46-53. They may be exactly the same for the 60-61 235. do you know?
Tim, Thats a great site. I had looked mine up some time ago on the inliner's site.
http://www.inliners.org/becks/BCN2.html My casting number from the block on the pasenger side matches one of three numbers for a chevrolet truck from 60 or 61 (3769716) but the number behind the distributer (F0603B) dosen't match any of them. So I'm still a little unsure what exactly I have.
