Muffler Hanger bolts don’t fit - correct Part#

[TPrelude-370z]

So to spare you the details, I’ll get right to it.

I purchased the 6 bolts that mount the L/R side rear muffler hangers (installed a couple axle back mufflers, and need the hangers to hold them up). I used the correct part number, and the parts guy at Nissan confirmed it. They don’t fit, not even close. The bolts screw in about 1 turn, and they are completely tight. I mean snap the bolt off if you keep tightening kind of tight. It’s a relatively long bolt.

I’ve mixed matched each of the 6 bolts/holes to confirm. What am I missing? It’s the same PN for the 350Z, and the G35. I’ve spent hours searching for an alternate PN, to no avail. I’m mechanically savvy enough to confirm a bolt does not fit. Amy help, or alternate bolts/sizes, would be much appreciated. Thanks in advance for your help.

Mounting bracket PN (don’t need) 20741
Bolts in question PN 081A6-8251A
