Cheap? Too much? I don't know I just saw it and thought I would share. If it was for a 29 it would be a good deal.
I guess if you need one the price is not too bad but it will need to be replated and the internal piece that locks it on the radiator is toast. I am also not sure that is correct for a 30-U either. I never had the original cap for mine as the original owner had a Motometer on the car. I have that cap but period pictures I have seen show a different cap. Perhaps they changed the cap style mid year like so many other things. If anyone knows the answer please share it!
The cap on our car looks like the one in the picture except it doesn't have the depressions on top its just smooth with the fin in the middle. I have no idea what it came off of except I'm pretty sure its not a 29. I think this is the 29 cap. I would like to find one but I probably wouldn't pay what they would want if I did.
