New hardware for transfer case skid plate

[Tob]

I'm about to install Savvy under armor, but I noticed it did not provide new hardware to bolt the skid to the frame nutserts. For 03-06 years, I read those should be M12 - 1.75, but I'm not sure how long of a bolt I'd need. The bolts in there from the PO have a longer shank for transfer case drop spacers. Will a grade 8 M12 - 1.75 hex cap screw and washer do the job? If so, what length am I looking for?

I ordered a new nutsert/hardware kit from @mrblaine, I’m sure he knows what you need.

No, a grade 8 Metric anything will not work because they don't exist. You need M12 x 1.75 Hex head cap screws in 45-55mm length Metric Class 10.9 or better. OEM has a captive washer if you can find it.

The OEM bolts are still available.

Thanks, I guess you can tell I don’t know much about fasteners

Why do I now feel like I need to replace all my grade 8 stuff with 12.9?

Because you don't know about F911 and L9 stuff?
