I was only able to get a 3/8" drive socket and using my 3/8" rachet I was noyt able to budge the bolts. I tried using my power bar with a 1/2 to 3/8 adapter (not best quality) and sheared the adapter using my power handle. Looks like I will have to look for a 1/2" drive 13mm socket.
I was hoping someone has done this as I would like to know if the bolts came out OK or did they shear.
Thanks in advance.
