Here's what I use. Lower... NAPA 7253 Upper for 45* water neck... NAPA 7575 (Gates 22417) Upper with straight up neck... Gates 21954
I used a Mopar straight up tstat housing. Cast iron not chrome plated pot metal crap. Made for a nice bend in the hose
I used 57 Chevy 283 upper and lower on my old 32 before i put the blower on it. My thermostat housing was straight forward and up at a 45 degree angle, and the rad was a center outlet on top. Had to trim them a little, but they worked perfectly. Tony
Go to NAPA with the measurements of both ends and they should let you look at their stock and find some thing that fits. That is how I found the hose for my 32. be open minded you might have to shorten one
