I made the lame mistake of not checking the size of the allen wrench to hold the top of the bilstein's before installing. I've done some searching but having a hard time finding it. I think it's a 7 mm but not getting a good fit. Anyone happen to know? Thanks in advance!

 

I had a heck of a time sorting out the right size tools for this. For anyone else that may want to know, it is a 5 mm allen wrench to hold the top of the shock and 17mm ratchet wrench for the nut. I ended up cutting the allen tool down to fit for the passenger side. For the driver's side, i found a little hole under the hood and was able to insert it from that side.
