Well I was installing the whole front clip on my truck. I had a buddy "help" unbolt& remove it months ago. All the bolts were tossed in one bag. First mistake.2nd mistake was thinking the bolts were coarse thread. So the front clip is held on by national fine thread bolts.7/16th NFT where the grill meets the frame; 3/8 NFT where the top&lower outer fenders bolt on.
I was putting coarse stuff where it should have been fine threaded.... Who woulda thought that? dang. [quote=
Thanks[/quote]
Yes I tried various bolts that I had until I had what I thought was "the one" .Turns out it is 5/16thNCT where all others were NFT- I probably should buy a tap&die set. blush

I posted here vs elsewhere thinking I would get a better more accurate response since I was asking specifically about a 58gmc truck.

wasn't looking for "the easy way out"-wanted to hear from people who have "Been there done that" with something in common- thumbs_up

Thanks 4 the advice; the clip is installed. cool
