          For this:
          Take Max up on his offer, because these are harder to find than Hen's Teeth and they should be at least 8.8 in hardness and Parkerized, so off-the-shelf soft steel Metric Bolts are an invitation to failure. I have dealt with Max on numerous occasions with sending and receiving parts ... tkoforpresident = A Very Trustworthy Man!

          P.S........... The bolts could use a dollop of Thread Locker (High Temp Loctite) and should be torqued down at 25 Newton-Meters ...or 18 Ft Lbs.
