My local hard ware stores dont have it and i would like to know the exact measurement of the bolt so I can order new set of 4 from Amazon or ebay. There's is supposed to be 4 of these alen key hex counter sunkbolts. Also tried to figure out the size myself by looking online and nothing also i wasn't able to figure out how to measure it myself I confused myself trying to figure it out. This is what it looks like I just have 1 because I bought it used and this was the only thing missing thank you.

Not my picture and i realized this one is not qsd just usimg as reference.

 

If the bolts that you are needing screw into the H22A block on the transmission end, they are 12mm x 1.50 pitch.
