Well, I been looking for a fan that would fit my Vortech S-Trim 8" rib set up. I finally found one today in ebay and i got it for $40dls after shipping, it is from a Taurus 3.8. I am going to order a DCC controler for it. I needed something that would push more than 3000 CFM's becsuse the weather in South Texas is always passing the three digits. My question is, Do I have to do any mods to make the Taurus Fan fit with my set up. Any advise is appreciated, thanks.
