Thanks again for all the input...much appreciated.
Regarding the shroud...it doesn't seem 'deep' enough to me...the fan blade barely fits inside...and the blades look they would be dangerous. I'm wondering if someone 'trimmed' this part down???
Can you confirm depth...?? current one is 2.5 inches...repro unit state 3.25...that would at least cover a little more of the fan.
Any clue what the fan I listed is from?? He should probably get the correct 772??
