Thank you, Motorman7! That's good to know. jdm-car-parts.com almost always inflates their prices by quite a bit, so you are probably right on with the $1,200.00 to $1,400.00 estimate. I've heard the same thing about re-chroming the Z hubcaps, they don't come out very well after re-chroming. However, I had a set of D hubcaps re-chromed and they came out looking beautiful!
It's funny how JDM Car Parts show that the Z hubcaps were for the '71 thru '76 Z-cars, which isn't correct per Zhome.com, as '70 and '71 240Zs came stock with the D hubcaps and the Z hubcaps only came stock on the '72 thru '75 Z-cars. They need to get their facts straight.
