After market heater core question.

[SKFengineer]

Our 1956 3100 truck came with the basic (non-Deluxe) heater core, looks like a donut, and basic fan package. The stock core started leaking on the way to a car show this fall so we are looking to replace the unit. We know there are several "Deluxe" options out there but this is mostly a fair weather truck so we don't see the need to follow the Deluxe route. In looking for a replacement heater core to our original unit we stumbled on one unit from "Classic Part's" in Missouri. Typically they are not my "go-to" for parts as I've found things can be hit or miss but I wanted to ask about the heater core they have listed on their site, has anyone used it? Seems like it would replace the stock fan motor unit and has duct outputs for the defroster.

In general I'm just trying to understand if this unit works and fits as one would hope understanding it's not the "Deluxe" system.
