Having a hell of a time finding the bolts that go through the straps on the rear of the car. 5/16 seems the closest but is not quite right......can't for the life of me remember what I did with the originals. Anyone know the thread size? I know I can take the starp to the hardware store but thought I would ask here first.
Thanks

 

The long bolts are 3/8 x 3.75" and the shorter ones are 1/4 x 1-1/8". Pics below of originals...you can see how the shorter bolts are unique.

 

Thanks a bunch for the info!
