rear piller bolt size ???

[rodstored-72]

all,
i am hoping that this is a easy question. i am needing to know what the bolt size is & threads for the seatbelt bolt hole that is located in the rear piller behind the seat??? (for use with a 3 point seat belt.) i think it typically has a plastice cover over it. it is the hole in the upper part of the piller...


thanks!!!!

The weld nut in the upper part of the pillar is threaded 7/16" x 20, NF thread.

I installed shoulder belts in my son's 71 C-10 and needed the bolts for the upper mount. I had some left over seat belt bolts with the 7/16 fine thread which fit the holes perfectly.

jim,
thanks again!! i hope i don't bother you too much with the questions..
what seatbelts did you use in your son's truck?? i have purchased a set from a mid '90's suburban..

do you think that they should work ok??

thanks again!!

I used a set out of a 93 S-10. I really don't know if the belts you are looking at will work. Maybe someone else will post the answer.

jim,
thanks! i am going to try to get them to work. the length is there i just neeed to get the base for each side to fit better on the floor. they are a little chewed up though. what made you use the s-10 belts?i would think that they would be too short? also how did the belts fit on the base in relation to te cab floor??

thanks again!!

well i dont know what happen, but i tried to put the bolts in ( 7/16" x 20, NF thread) and they do not fit (thread part) is it possible that the threads are different on my truck??? i don't know if the bolts are ""nf thread"" though.....


any help would be greatly appreciate!!!

thanks,

Wow...you just got around to this 5 years later?

7/16 20 (fine thread) is the correct size bolt for the pillar in all 67-72 trucks.

well not quite what it appears, the truck has been put alltogether test drivin' & tore down for paint & body and now back together. i "lost" the bolts bought new ones & now i cant seem to get them to thread in what does the "nf" thread mean? should i just "wrench" the bolts in to make them work?? i do not have a tap that size, & would prefer not to buy one if that is all that is needed.....

thanks!!

7/16-20NF = national fine which is 20 threads per inch on a 7/16 bolt.. You will be better off if you can find 7/16-20 seat belt bolts because they are a shoulder bolt. Those holes would be hard to repair if you "wrench" the wrong bolts in.

john, how would i go about finding these seatbelt bolts????

thanks!!!
