Tow Hook Bolt Pattern?
Maybe some of you guys that have a pair of 71-72 factory tow hooks can help me out. I'm trying to find out the 'center to center' bolt hole pattern for the front hooks for my truck. Are they 4" center to center, or something else? Did the factory drill them at an angle or straight up and down in 1972?
Thanks for your help and I look forward to some good feedback please. 72longbed |

Re: Tow Hook Bolt Pattern?
On my truck the holes are in the frame. They are angled back.

Re: Tow Hook Bolt Pattern?
Right Ozman ... in the frame. My question is how far apart are the holes? If you measured the center of one hole to the center of the other hole, or the bottom of one hole to the bottom of the other hole, what would that measurement be? That's callled the "bolt pattern".
Is the top hole farther back than the bottom hole, or the other way around? Thanks. Last edited by 72longbed; 01-05-2011 at 07:16 PM. |

Re: Tow Hook Bolt Pattern?
Here are some pics that I have saved of the '72-only extreme bend hook mounting location. I don't have exact dimensions, but take note of the bolt pattern on each frame rail and how one is mounted higher than the other.

Re: Tow Hook Bolt Pattern?
Good Deal Gene .... I get one more 'owner' to confirm, and that's the measurement I'll go with.
Thanks Boss! 72longbed |

My Thanks to ALL !! 3.25 is what I'll go with. It looks like the upper hole is back about 3/4 of a hole from the lower one too.
I appreciate everybody's help! 72longbed |

Re: Tow Hook Bolt Pattern?
I take it you dont already have a set? if thats true I would hold off on any drilling till you get them..they are a very tight fit and almost touch the bumper and are pretty close to the springs. The best way is to just hold them up against the frame with your bumper mounted and find where they fit the best...if you get the holes to close to the upper or lower frame rail you wont be able to get a nut on the backside.
The 69 to 72 use the same pattern as the 72 only...but I dont remember one being higher than the other like in sdaileys pic.

Re: Tow Hook Bolt Pattern?
Good Advice ... I'll be sure to do it that way when I can finally find the hooks I want.
Thanks. |

Re: Tow Hook Bolt Pattern?
Take a look at post #23 in the link below. This is where I found the bolt hole mounting pictures and information about how one hook mounts higher than the other. Being that Frank (pickmup) posted this information I took it to be gospel, especially since he said they were listed on the SPID.

No problem Rob. I never took it as you doubting me. I just wanted to throw this info out there as well and confuse everyone a little more. I have a set of exteme bend hooks that I'll be mounting on my '69 K10 and it doesn't have any predrilled holes for the hooks. My plan was just to mock them up and drill holes, but then I came across the link I posted above. I've never mounted as set of these hooks, so I'm new at this as well.
