What's the part number and NSN from the parts TM?

nsn 5306-01-157-3279 , gm 471083

Not finding anything through parttarget.com ( usually a good source ).
All the GM searches come up as a obsolete part.
I did find this in a GM parts catalog [ 4 16 714 BOLT HEX 12X1 75X35 CAD ]

But will he ship them to europe ?

Won’t know until OP asks him

From the info PP posted,

12 mm X 1.75 thread pitch, X 35 mm length

It should be readily available in Europe.

I just happened to have mine out.

It is indeed a 12x1.75x35mm with a hex head 22mm(7/8")



They are, however, slightly swaged into a triangular cross section that acts to lock them in place.



It may well be a common "seat belt bolt"

You might want to use locktite on any non-swaged replacements

Thank you all for your great help !!!

I hope to find them available here as they are not a hard to find size...One more question : are 10.9 grade bolts suitable ?Also seems too much to ask someone to ship you two bolts overseas...

Happy new year !!!

10.9 should be fine . It seems while I was searching it came up as grade 12. As was mentioned some blue locktite might
not be a bad idea. I try to stay away from the red locktite on anything that may need to come apart again , unless it is a easy location to apply heat.
