1998 Park Ave ,not Ultra with 3.8 L . The mount that is at the water pump location one bolt broke recently ,the the other one broke sunday .The bolts are the ones that connect the halves together they are vertical ones , not the studs that bolt to the engine or carriage bolts that connect to the frame.I was thinking about using hex bolts , would grade 5 be strong enough to hold?

Thanks
LMG

Yes, as long as you install the complete wiring harness, PCM & CV shafts from the PAU.

I need stud num 22 where can I get it
Some well equipped hardware stores have studs in stock, but that particular one may be hard to match! It may require a visit to a local machine shop to match the stud size/length & threads.
