Blower motor resistor

[Madsen1970F100]

During my rebuild I accidentally messed up the heater blower motor resistor. I looked for ideas on here but still am confused and thought I'd post an inquiry.

FIrst, is there anyplace to get these things anymore? One link I found asked for ford part #.... anyone know what the part number is for this? Its a 1970 with 302, 3-prong deal.

Second, can it be installed without removing the entire heater box? Just a question to avoid disconnecting hte heater core hoses and such, being lazy.

Third, is there some description for a creative engineering rig using some resistors one could get at radio shack?

As it is I just disconnected it and have the fan on full blast or off. Thats fine for me really but if I can rig something up or pick one up nad get it done right, that would be better.

Thanks for any insights....

I'd start searching through the local junk yards for one. Find two and take the second one to an auto electronics place that can make some that functions the same.
