Purely FYI. I largely followed the JTR book on cooling by purchasing the Mid 80s Camaro radiator and by using the JTR radiator cradle. I have one of the older galvanized steel cradles so it may look a bit different that the newer ones made from aluminum. Be careful about getting the correct radiator; the JTR recommended radiator is more expensive that the larger one of the same vintage. I picked mine up off of fleabay for ~$110.00. The only thing about using the Camaro radiator is that its next to impossible to find the rubber isolators. I ended up using a set of urethane isolators (under $18.00 from anywhere), cutting them to fit and using a silicone adhesive. Works perfectly.
I made very simple mounting tabs for the fan using some 1/8" angle iron. I drilled and tapped them to mount to the cradle, but you can use a method that works well for you.
WRT the fan, I really like this one since it completely covers the radiator like it was meant to. You will need to cut of a few of the mounting brackets to get it to fit.
I do recommend reinforcing the top of the JTR cradle using a thicker piece of aluminum sheet for backing. This radiator and fan combo is a bit heavier and there is some flex in it that I didn't like. Simple hand tools work and I riveted them on to the cradle.
