SUMMIT RACING has a big listing of fans, including reverse rotation fans.  I know they have flex fans, but did not pay any attention to see if they have non-flex ones.

Thanks for the info.  I looked at the summit website but it didn't give any info on the overall area taken up by the fan front to back to see if I do indeed have enough room.  I think they would work, but before I order one, I would like to know if it will hit anything.  I tried to find a phone number for them, but there wasn't anything on their website; at least I couldn't find any.  Thanks again

Go to Derale.com.  Two things to look at.  First, click on the support center tab in the upper left and the click on sales support over towards the right.  Numbers are listed as well as an email contact for support.

Next, click on the products tab and use the scroll bar below to get to page 61.  The depth for each fan is listed.  If you see a part number there that is not on Summit, you can still order it through Summit.  They range from 2-1/4 to 2-7/16 deep.  The site is in silverlite, apparently, and you can't copy/paste info - at least from Chrome.  If your system does not support silverlite, it may not display properly.

The sales support number listed is:  323-266-3850

What diameter do you need?  Thanks for the info.  I tried their website and ran into the "Silverlite" and I finally called them and  they told me on the part I was looking at it is 2 1/4 inch.  I am looking at their p/n 17417 which is a 17 inch.
