63-66 bumper hole spacing
Can anyone tell me the spacing between the holes in a front bumper? The 60-62 has a 26 1/4" spacing. I'm hoping the 63-66 is wider and will fit my non factory frame better.

Re: 63-66 bumper hole spacing
I remember hearing folks at a cruise last year talking about the difference in the rear bumpers because of the frame width difference. I know that the 60-62 are narrower in the rear. so I am thinking it is probably the same up front. Unfortunately I do not know the dimensions to help.

Re: 63-66 bumper hole spacing
I apologize for such a slow response to your simple request. I have measured both my '62 and my '66 and they are exactly the same at 26 3/16". Good luck.

Re: 63-66 bumper hole spacing
Thanks for checking.
If the spacing is the same, why do they sell two different bumpers? Is it the side support hole? Posted via Mobile Device |

Re: 63-66 bumper hole spacing
It's the front bumper I'm interested in. At Classic Chevy Parts they sell a front bumper for 60-62 and one for 63-66. http://www.classicparts.com/Bumpers/products/242/
What's the difference? |

Re: 63-66 bumper hole spacing
how can you tell what year of bumper you have. My registration says it is a 63 but it has a 62 grill and torsion bars.

some places didn't register the year until it was sold. if your truck was sold in oct. 62 say when the 63 production was out, it got registered as a 63 ron |

Re: 63-66 bumper hole spacing
I don't have the dimensions for the different front bumpers handy, but I can get that info tomorrow if someone else doesn't beat me to it. The rear frame on the '60-'62's is wider than the '63 and up trucks. The side to side hole spacing on the '63-'66 frame horns is close if not the same as '67-'87 trucks.

Re: 63-66 bumper hole spacing
Ok, I have an answer. The holes are the same spread width-wise on early and late front bumpers. What differs is the spread between holes vertically. early bumpers ('62) have a spread of about 3 3/8" center to center, with the upper hole center down about 3 7/16" from the top edge of the bumper. On later bumpers ('65) the vertical spread is 4 7/8" c to c with the upper hole center at 2 3/4 down from the top edge. If there is a difference in profile, it's not easy to see without a cross section comparison, but the difference in hole spacing is plain as day if you look for it. Funny how you don't notice some things until someone suggests you open your eyes. So lame it took this long to get you that info. Hope this helps

Re: 63-66 bumper hole spacing
here's a '62 and a '63 for side by side comparison. not very good pics, but you can easily see the difference in spacing.

the vertical distance does make sense as the earlier frames are not as high as the later frames ron |

Re: 63-66 bumper hole spacing
After learning the information from above, mine must be a 63-66 bumper on a 60. My frame is not original. Thus it could have came from any year. It's good to ID the bumper since I want to put the matching one on the rear.

Just wanted to verify that Ron (padresaq) is correct regarding the different shape of the 60-62 to the 63-66. Although width wise the front of the 60-66 frames are the same distance apart laterally, the space of the bolts vertically are different. Also as Ron mentioned; the shape/contour of the 60-62 bumpers are different than the 63-66. I was hoping to use a 65 cut off section of the frame horns on my 62 frame to repair my cracked 62 frame horns, but the cross section contours are different. Also, you can see this shape difference if you look at the side by side comparison pics that oem4me posted,
