sorry it took me a min to get back, been out for a few days, if you using anything other than the stock radiator, you gonna end up fabbing up mounts. i happen to like the griffin race radiators, an any fox chasis works with the ford engines, or look in the jegs catalog for the size you need. i dont remember exactly wich i used...its been a while an my truck is back in pieces again due to lack of time to put it all back together
