T radiator A chassis

[1ton]

I have a '27 roadster body just sitting around. Recently acquired a running '30 chassis. I'm thinking about mating the two together. The plan is to keep the chassis all original, mechanical brakes included, and use the original T hood and radiator shroud. My question is about cooling. Since I don't have a radiator and would have to buy a new one, would the smaller radiator cool the A engine enough or should I plan on a '28 '29 radiator and shroud instead.
