72 spring eye bolt size

[westong]

I left the house with out grabbing the front spring eye bolt on a 72 blazer. I need to buy a replacent as the one was stuck in and had to be hit out with a sledge hammer. Any one know the size of that bolt? My house is about 30miles from the store so trying to save some fuel...thanks

9/16-18 x 4 1/2" or 5" i think. at least for the fronts. the rear is the same.

the shackle bolt on the front is 7/16 diameter.
