yes I'd like to run a shroud but the rad has no mounting provisions for one. not sure the brand (champion maybe) as it has a champion cap but no markings anywhere on the radiator which I thought was strange & I think I read that champions have their marking on the bottom but nothing there.
Instructions on my new clutch fan say say the fan should be at least 3/4 inch from radiator
If you run a shroud, edge of fan 1/2 inch inside shroud opening
