Heater Control Panel
I had three to chose from -
1) panel from 1968 1750 Spider s/n 10557.1410461. This was a spider originally produced for sale in Germany. Unfortunately, the PO had wrecked it into a brick wall and it was parted out
2) panel from my 1967 1600 Spider.
3) panel from 1966 1600 Spider, s/n 10503.660473. It had been almost completed stripped when I bought it for the few remaining parts. I ended up selling it as a rolling chassis.
In the photos, they are laying left to right - 1968, 1967, 1966
The German car's panel doesn't have the bracket for the Emergency Flasher toggle. I believe those were only added to the cars destined to be sold in the US. Otherwise, the 67 and 68 panels are nearly identicle.
The 1966 panel has different internals and is the design that is depicted in the 1600 Spider Spare Parts Catalog.
I don't know why the original design was replaced. I actually think it has advantages over the later design.
The early design uses a "Ball and Detent" type of mechanism that locks the levers in the leftmost or rightmost positions. The later design doesn't lock into any position.
Also, on the early design the levers are completely independent from each other. Moving one lever can't effect the position of the other lever.
On the later design, the 2 levers pivot on the same shaft. There's a fiber disc separating the levers and moving one lever tends to shift the other lever.
So, I decided to clean up the 1966 control panel.
