Speedway always has something (aluminum) for that app. Call & ask... they'll fix u up if you want something new, I bought mine on sale! On the Daytripper I used one from a mid 60's Chev truck but I was running a SBC. They also have cheap ones on daBay! You also didn't mention if u chopped the rad, they have lots of those on daBay too!
