IT'S TIME TO CHANGE MY 66 RADIATOR NEED INFO ON SUMMIT ONES

In 2000 I replaced the 2 row radiator on my 66 coupe with a 4 row unit that I purchased from the Pony Car Store. The unit was built by Radtec and has worked flawlessly for 10 years. Last Saturday my fan clutch broke and it was so close to the Rad it broke 5 lines and scratched 3 more. Since its 10 years old and I only have a 289 hipo with A/C with a hydraulic version of the hipo cam I think that 4 rows won’t be needed. I was looking at Summit Racing and they have this 3 row for 170.00+ shipSee below)

I have never used one of these in any one of my cars and it will save me $65.00 dollars cuz shipping and handling to my place from summit it's about $60.00 bucks. The sales rep @ summit said that they had excellent feedback on them on fitting and performance. I need some feedback if any one here has used or installed one of these. Thanks in advance!

I forgot to mention that I am looking into a standard fit without cutting the core. So the 67 20" radiators cannot be used unless some cutting and changing batt tray it's done.
