While doing work on the car I messed up one of the bolts on the front upper strut tower brace/bar. I want to replace it, but I'm having a hard time finding the part number for it. Does anyone know? Thanks

 

Unless I'm missing the location of the bolt, I'm not sure the ones that hold the front shock absorber housing to the strut tower bar are serviceable. If you go to a parts site like AcuraPartsWarehouse.com (not an endorsement, I just like that you can zoom into their diagrams), put in your model and year and then look in the Front Shock Absorber section, you'll see a breakout of the parts. And #7 is the shock absorber mounting. It appears that part includes the bolts that extend up through (and attach to) the strut tower bar.
