I'm way late seeing and commenting on this post from Nov, but that shroud hasn't been cut. Ford used radiators with 2" top channels and some with 1" top channels. The radiator shown has a 1" top channel, but the shroud is for a 2" top channel radiator. My '01 has the 2" channel and my '02 has the 1". The cores on the original radiators are 1" regardless of the top channel.
Regarding toppers - I have one on both my trucks. I searched Craigslist everyday for 16-17 months before I found the ARE for my '02. I searched in a 2-300 mile radius, and eventually found one about 6 miles from home for $600 in 2014. I was happy with the 1 piece cover on my '01, and the factory cover after getting one when I swapped beds, but occasionally needed a topper for work (or drive the '02 everyday), and I was fortunate to find one locally in about 2 weeks that I have about $150 in. It's some off-brand, and not ARE quality, but it matches my truck. I've had toppers on every truck I've owned except my 1st one, including 3 Rancheros and 3 F-series, and I would take the toppers off once in a while just for a change. The topper has been on the '02 since I bought it in May 2014, and the topper has been on the '01 since I bought it in the spring of 2018. I sometimes think of taking it off the '01, but probably never will. They're just so useful and look so good!
Changed the dangerously cracked fan on the '02 last week.
