Drill hole in front spring hanger

Here is what I did and these were for springs with large eyes front and rear . I never saw them large front small rear except for stock 73 up. But I won't say they didn' make them. You can use the small shackles to install the springs with the large eye. But if they are the large eyes with the large bushings the shackles will be loose in the spring. The bolt is 9/16 for sure . 9/16 hole will be excact. 19/32 will be 1/32 over . I prefered to be excact but to each his own. 19/32 will work and be easier to get in. Here are some picks of the different hardware for both style springs. Bolts are taken from a 73 up car. You can also use the front hangers form the later cars These are early drilled. Just some friendly info that might be useful. I do have any hardware needed. at this time. Steve
