need some measurements

[johnd]

I need some measurements for where the antenna is placed on a 75 vette, sometime ago the antenna was shaved and now the owner wants a new one put in so can someone help me out...say from the body line and from the rear bumper?

Thanks,
John Dykstra

I have an orginal 74 so there is some risk it change in 75 but not much risk.

I measure 8 inches from the bumber and 2 7/8 inch from body line for the center of the hole. I will attach pictures so there is no confusion.

Doing some rear work on mine now and the antenna and bumper are off. I get 8-1/4" from the deck/bumper seam and 3" from the fender peak to the center of the hole. Guess GM did not really use an accurate template to cut this hole.....
