fan shroud question

After more poking around, it appears that a 26" shroud for a 70-73 Big Block B/E body will do the job. The overall dimensions make sense and it seems to place the end of the funnel (for lack of a better term - I'm not a radiatorologist, nor have I played one on TV) at ~3" from the face of the core. This is about dead-on in the middle of the existing fan setup.

I've ordered part# 2998326 from Mancini and will post an update after installation. The next several paychecks could very easily be diverted to Mancini Racing if not for frivolous crap like the mortgage. O:)
