'69 22" fan shroud & brkts ???

I have a plastic 22" fan shroud (# 2998325) off a '70-'72 A body.
Thinking about adding to a '69 Road Runner; it looks the same as the B shroud, except it has some serrations for the upper tank "ribs".
Shouldn't be hard to sand those down so it fits the rounded tank.
Anybody out there have one on theirs ?
I need to know the measurements of the shroud mounting holes/studs.
I can buy a bracket set from Classic ("fits '69-'74 B and '70-'74 E"), but I'd like to be sure they fit this shroud.

Or maybe I should trade it for the dead-correct part...

Mancini has dimensions for the repop part, should be the same since it fits the a-body radiator.

Thanks, Bob -
That's the shroud I have, just wondering if the B brackets position it correctly.
My Duster's OEM radiator had tabs instead of the add-on brackets.
The '69 B 22" radiator requires the brackets.

A Body radiator is shorter than a B body radiator I believe from looking into getting a radiator to put in my Big block A body.
