I think it was a 19x27, I used some molded hoses. The nice people at Napa let me go to the back and look at all the hoses, I found a set that works perfect. Its pretty easy to make the mounts, just get some 1/8"x 1.5" flat stock, put a 90* bend in it and drill some bolt holes. Make sure to put a piece of rubber between the radiator and anything it contacts, as the aluminum will wear away if its constantly rubbing/vibrating against anything. Its real easy to do the swap, just dig in and do it.
