Rear Shock Bolt Size?

Does Anyone Have The Measurements
Of The Rear Upper Shock Absorber Bolt On a 1969 Roadrunner?

Thank You

I believe 1/2 inch by 2 should work.

The rubber bushing has a 5/8ths" hole and it's 1 5/8" long uncompressed.....

Edit: Been too long since swapping out shocks but the upper holes on my 66 look to be half inch. Are the uppers supposed to have a steel bushing in them? I have a set that have a bushing and a pair that doesn't but I'm thinking they take a bushing....and the bushing is 1/2"

Believe these are the original upper shock bolts on my 69RR. 1/2-13 x 2.75…….I’ve also seen the hex heads marked with an M with 3-hash marks…jim
