Thanks, guys. I don't know if the 55 is passenger or truck. I read that for 37-40 I needed a 41-54 wide-tooth #139 flywheel. I found one a while ago with the correct tooth count. The 55 was stripped of intake, exhaust when I got it. The 59 will help out there. I have thought of putting the 55 in as is, because I was told it was rebuilt once. But I have been burned on that story before. I might build a stand to get it running and check compresson, etc. I guess I could take the pan and head off to see what things look like also.
