Rear bumper bracket holes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

focusedontheprize · 01-28-2020, 10:45 PM

I am currently fixing the rear frame rails on my ‘88 V30. I noticed that I have two sets of rear bumper bracket holes (1 1/4” apart) for my sport bumper. Could anyone recommend which set I should be using? I trimmed the rear frame rail, but can add material back if I should be using the front set. Thanks.

Thank you for this. I will have to check the channel and video out.

Thanks again for sending this link. Unfortunately in this video they cut out the forward bolt holes that are used for the tow hitch (which I am using).

Can anyone provide a measurement from the rear edge of the frame rail to their bolt holes?

I got some pics for you from my dually. I added some text to help w/the numbers. 1, 2, & 3 are the bolts that retain the inner & outer brackets on mine.

#3 is approx. 5" from the edge of the frame rail & only goes through the last hole on the inner/longer bracket.
#2 is approx. 1.5" from the edge of the frame rail.
#1 & #2 go through both inner & outer brackets.

Thank you very much SCOTI! Neither of the set of holes reflect those dimensions, so I am going to plug weld them and probably have to start fresh. I appreciate the information.
