I ran the Fbody fans on my '92 with a 34" radiator. They worked great but I wasn't running A/C.

You will have to fabricate mounts or use radiator zip ties like they sell at the zone, through the radiator. I always have problems figuring out how to seal the top of the radiator off for air flow. If you have a metal brake there at the body shop you should have no problems making something if you can just modify the stock pieces. I'd got for a new 34" radiator and 2005 electric fans with Allens fan harness. That will look so factory stock instead of hybrid as the LS1 fans would be.
