Hello all. Does anyone know of anybody who makes/sells an adapter to put a 26" radiator on a 22" core support? Thanks for any help.

I don't know of an adaptor, but I put a 24" aluminum radiator in my 22" opening and the core fit the 22" opening perfectly. With a 16" puller fan on one side and a 16" pusher fan on the front side it cools my 440 in 95+ degrees stop and go traffic all day long. I used a SPAL fan controller with pulse width modulation so I only get as much fan speed as I need.

I installed a 26 in place of a 22 and all's I did was mount it on the driver's side bolts,level and mark/drill holes on the passenger side. Worked well with shroud and 18 inch flex fan..no problems..pretty simple
