Hey, that was one of my auctions. I'm the seller of the second auction link you posted, the one "that will bolt right up to a 5.0". I think you may have misread my auction, I mentioned at the bottom that I also sell the Mark VIII fans ready to bolt right up to the 5.0. That one for 99.99 has the tabs trimmed off and the shrouds reduced in depth and would just need some type of brackets to mount. I sell them trimmed with the stainless steel brackets ready to bolt right up to a 5.0 like the one pictured below (minus the overflow and DCC) for $125 plus shipping. If a DCC is a little to pricy for some, I also sell simple 2 speed controllers for $25. I use a Mark VIII fan in my 92 GT it it really works awesome, I have flow tested the fans and some of them even flow close to 5000 CFM. In my opinion they are definatly the best choice. I also sell the 3.8 Taurus fans for $65 that someone else mentioned, which flow about 3500cfm. Here are some pics of my fan install with my DC Controller mounted on the inside of the shroud, like Baskin does.
