The top of mine has a pair of adapter plates that hook to the Carolina Customs hood top mounting bars that brace back to the firewall. I didn't use any rubber at the top.
For the fan, mine came from PRC with a shroud made from a sheet of aluminum with a 16" hole matching the fan diameter. At the top and bottom they bent over a nominal 1/2" tab to close the space, and on the sides the made a similar 90 degree bend with a nominal 3/4" tab, then bent out a 1/4" mounting flange which aligns with the two mounting channels on the sides of the radiator. This gives a little "box" that sits 1/2" off of the radiator core, matches the core area, and has mounting flanges that are held to the radiator with four 10-32 screws near the corners. I've had zero problems with over heating using this shroud, and my unintentional "test" was forgetting to hit my "ACC" button one day, and noticing the pegged temp gauge after idling in traffic for a few minutes :eek::o:o Punched the "ACC" power, and watched the temp gauge start falling within ten seconds, and sitting at 190F within less than a minute.:D Proved the goodness of a shrouded fan to me!!
