I dont have a build sheet for the car...I sure wish I did. Its a San Jose car and from what I heard they are harder to find than the other sites. The numbers are only on the 1 blade, and I have seen other that had the upside down R for the H, but not a pic like mine with the upside down R that was X'd out then an H next to it. This was not a restored car...built and sold in San Jose and I bought it there 31 yrs later in rough but fairly complete shape...so having these parts on it is far more beleivable than a restored car.
As far as measurements, I will try to check it today. Thanks for the info on the original spacer that others had. Until I know more about SJ cars I will use this as the fan spacing is correct and I would hate to pitch a part that I find out 5-10 yrs from now was correct.
