I'm getting ready to repair my 40 year old heater, besides the heater core and electrical switch, what other parts should I expect to change out?

Well that depends on what is wrong. How do you know you need a core and a switch. The two would be for unrelated problems

While I had it apart I would also replace the blower motor.

It the process of replacing the interior firewall pad, I noticed the heater switch had deteriorated, literaly fell apart (appears to be original switch).

As far as the core, I was advised that it would be a good idea to replace it while I had the heater unit out.

If there are other 40 years old parts that could possibly be replaced while the heater unit is out, it would seem to be a good idea to replace them, especially if they are inexpensive parts...

Well if you have the core out, you could just take it to a radiator shop and have them clean and presure test it. If it is good it is probably better than any replacement you will get. Everything else is pretty easy to get to like the fan and the fan resistor so they shouldnt be bad to replace if they fail later

replace or repair

I would look into a replacement core. The old unit has served its purpose replace it.

Same here. Chances are a replacement is gonna be coming straight from China, and while they can turn most any product into a pile of junk that looks like it oughta work (but doesn't), they really excel at making the worst motors on the face of the earth.

get the core tested
new hoses (rubber gets funny with age) and switch (as it's falling apart)
The motor might be serviceable- brushes and stuff. Does it spin with little resistance? If it spins with little resistance and responds well to 12v power, then I'd keep it. Put the money into a nice paint job or something.
