Fan shroud questions.

[bob_o]

What's happening out there in Square Land? I'm curious about something... Why is it that a fan shroud for a '75 1/2 ton with a sbc is damn near impossible to find? Nobody (that I know of) re-pops them and I have been unsuccessful trying to locate a good used one. What's so different about a '75 versus '73-'74 and '76-'80?

I bought a two-piece sbc shroud and upper bracket from a late 70's c10 and the shroud was almost an inch too tall?? I trimmed as much as I could off of the bottom (about a half inch) but then it was bottoming out on the chassis. The bolt holes for the upper shroud were still over a half inch higher than those for the bracket. Dafuq? Am I using incompatible parts?

Here's the upper bracket:

Thanks in advance!
