I have 16 NOS GM wheel studs PN 3980406 7/16 x 20 x 1 3/4.
My info shows they are for 1971-72 C10 (4/WD) and Blazer.
I believe the only difference between these and 2wd 6 lug trucks is they are 1/4" longer.
If I am wrong I will buy them back 100% guaranteed.
$5 each or $50 for all 16 pieces, in 3 GM boxes to your door, no bar code NOS here real old school NOS!!
To your door = in the 48 continental states
If you dont like the price make an offer ! Thanks -Dan
Paypal is preferred but I will accept MO and P Check (hold till clear)
