What is the frontspacing dim on orig 15X7 Rally

[rd1970gs]

Can someone tell me the dimension from the front outside lip of the wheel to the flared bolt hole on an original 15X7 Buick rally wheel. This is the front dimension, if you want to let me know what the orig backspacing should be on the original wheel that is cool to know, but I really need it from the front at this point.

Thanks a lot.
