I wonder how rare the 6 cyl Thermactor actually is? Or, rather , 6 cyl cars that have a functioning thermactor system still in place.
Not very if the car has the right DSO. Would guess that there are fewer 6 cylinders that came with the system with them removed compared to the V8. Its just that those that get to view most of the Mustangs only at shows and the internet see less since they are less popular to restore and have as a hobby or club car
Also agree that the indexing washer is likely exactly the same and it was used in later years also - opening other possibilities
I would be interested in a complete thermactor set for my CA car, but looks like it's very difficult to find one..!!
Well sort of. First there are less people saving and collecting them since there is little call for them. Often they are donor systems for V8s or simply tossed or not removed when found. Typically 6 cylinder parts in general are 10-25% of what the same V8 part is - even NOS parts. Have purchased V8 radiator hoses in the over $300 range (seen them out there up to $600) and have purchased 6 cylinder ones for $20. Just depends on how much you impress to the seller that you really need have to find, I've been looking everywhere and how much they choose to capitalize on that or an accent
Where most of these pictures were taken I would guess that you could have purchased the system for a very reasonable price. Of course a digger out in the yard looking to resale will/should be looking to at least double his dollar or more considering how much effort it took to remove and how complete. Think the challenge is finding one for sale rather than the price.
Guess a huge quantity of cars were sold in CA, and many of them dismantled the Thermactor system so, where are all of them..?
Try all of the cars sold in CA about 20-23% of total production) were required to have the system. As I wrote above I would guess that more 6 cylinders today have the system in place than V8 cars that came with them originally
