The Champion CC526B is a good fit. I had to elongate the slotted holes a little, but not a big chore with aluminum. I used upper hose Delco 26029X and lower Napa 7695. A couple of inches had to be cut off the radiator end of both, but the shapes are right.

Now the problem is clearance for the fan clutch. Clutch mounting surface to radiator core is 3.15". The Hayden 2947 low-profile clutch is spec'd at 2.71" overall, for a clearance of 0.44". Is that barely acceptable?

The alternatives, and I don't really like either, would be electric or a flex fan and spacer. Which of the three sounds least bad?
