Hello. I have not posted on this site for a while as my Pathy was down. Now the 8 bolts on each end of the front differential that mount it to the frame have been lost with the engine swap. Does anyone know the length, size and thread pitch of these 8 bolts? I think all 8 are identical. I have called and searched online for 2 or 3 hours. Nissan dealers don't even ID the bolt with an old part number, much less help with anything else.

If someone could tell me the length, size and pitch I will buy some grade 8 bolts to replace the lost ones.

I'll submit a diagram and an old pic of the bolts I'm talking about. Thanks!

Part number is 54726-0W005, but I suspect they're no longer available.

Factory bolt is a M12 x 1.75mm x 25mm flange bolt with an extra 5mm unthreaded tip.

Awesome that will help me get replacements! Thanks a bunch. Nissanpartsdeals.com seems to have them for $2 each.

Yeah, I use NPD for all my part look-ups, but their sister site InfinitPartsDeal.com has them out of stock/discontinued, as does Nissan's official parts site parts.nissanusa.com, which is where I buy the actual OE parts from. High probability NPD will accept the order and then cancel it.

I highly recommend either McMaster-Carr (mcmaster.com) or Bolt Depot (.com). I buy practically all my hardware from them since local suppliers tend to suck. They both have 30mm class 10.9 yellow zinc flange bolts (McM p/n 93474A232; BD p/n 17521) for about $1.25/ea, though McM is $12.55/10 bolts if you don't mind the extras. Both ship for about $7-$8 either UPS or USPS.

Thanks! I had a moonlighting mechanic swap motors and I've found about 8 bolts/nuts missing or loose so far. Do you know the sizes of these nuts by chance? I'll go get all I need at Fastenal which we have here thanks to the oil/gas companies. It's the nuts that go on the very bottom of the left/right front motor mounts, and the nuts that go on the very top of the nut also. Shown below. 3 of the 6 are missing. Ugh...

Those are M10 x 1.25 flange nuts; don't recall what made them different in terms of OE p/ns, but same thread.
