70 Coronet Small Block Cooling Fan Size

[HemiJJ]

My 70 Coronet had a 74 28in setup transplanted at some point and it recently sprung leak. I'm going back to a 26in like it would have had in it. The OER shrouds have a 20.25in opening but my fan is all of that in not larger. I'm guessing the 70 318 had a smaller fan. Anyone know the size (maybe 18in) and have any leads on one?

Thanks!

I think I discovered the correct one and snagged one off eBay. I got an 18in 7 blade 46237. I will let you know if that does not work out.
