biscayne heater

[digger]

Hi, I have a 58 Biscayne with the basic heater system with just the 2 slide control will the 4 slide control as found with the deluxe heater system fit as a simple swap out

I would not think it would. The whole heater box is most likely different. If you want the better heater, just look for the deluxe heater box and swop it over. I would guess the heater core is the same, but that is probably where it ends. If you have a assembly manual look under options it will show the deluxe heater.
