So I had a similar issue with my fan switch. I discovered there were no new ones to be had and I hesitated to put in another 45 year old switch from a scrapped car (not to mention people wanted a fortune for them). I chose to replace it with a modern 3 speed switch. I purchased mine from oldairproducts.com. I no longer have the infinitely adjustable fan speed, but I have reliable high, medium, low. Existing knob fits on the switch.
I believe the other switch is a simple thermostat with a capillary tube. They also sell those with either an 18" or 48" capillary. 48" is probably longer than you need, but pretty sure 18" is too short.
BTW, I also replaced my AC blower motor with one for a ford mustang (I forget which 60's vintage) and it works great. Same connections and similar mounts.
If you are looking to stay "original", I can't help.....sorry
