hello everyone and thanks for accepting me in the forum. I own a 2003 h2 ( by the way best truck I have ever owned) and I need the size of the front bolts on the skid plate. I have tried 8m and 10m if anyone could help a girl out it would be much appreciated. Had some work done on my truck and the guy did not put back all the bolts. Rattles and is driving me nuts. Thanks in advance for your help

 

I think they are M10-1.5 X 25 mm long, grade 8 bolts if I remember correctly but if they overtightened them they may have stripped them out hence why they are missing. I think they go torqued to 22 ft pounds which is not much.

 

Those specs are correct. They are GM part number: 11518341 and can still be purchased
