I need a few pictures of the long front bumper bracket bolts/washers used to attach to the extensions. Not sure if they should be flat and a lock washers or a round serrated type washer. Looks like their are 4 bolts.
When I took mine apart, the frame extensions, (2 bolts per side), had regular flat washers and lock washers, and the front bumper extensions had the serrated washers on both bolts on each side. In another thread Alan71 posted pictures of his car and I don’t believe it had any serrated washers. Not sure if mine was a virgin or not but the bolts were most definitely originals. I will be anxious to hear what others say as I will be reassembling mine soon.

Thank you Bill and Terry for taking time to relay that info as well as the pictures. People don't realize the time it could take to fish out pictures or stop by to answer your question. Greatly appreciated! Bill I will maybe get a few more pictures. I thought the donor car I had did have 2 serrated washers.
So I have 4 complete sets of the bumper brackets and of course I chose the wrong ones. Finally found 2 that actually match the part numbers in the AIM. Terry you picture does show flat and lock washers like both of you and Dub mentioned. The only thing I notice is the bracket has 2 elongated holes which is different. Pictures after lunch (phone dead)
This is the bolt and serrated washer that were on all 4 front bumper extension bolt holes on my 69. Apparently the 69 front bumper extensions were one year only. I think it was Bairs that told me that. My car also had the elongated holes in the bumper extensions. If you want a picture of those I have them close by and can easily snap a picture. The elongated holes is why I think the serrated washers would be needed.
Edit: Third pic is my left side bumper extension. # is 4257L
Okay, so now I have a few different opinions going on. TTop I can see why the serrated washers may have been used with the elongated holes. Makes sense.
So here's what I have:
So in the last picture the painted ones on the far left are actually longer then the others so they are out. I have a set with elongated holes with the correct part number from the AIM. I also have a pair without the elongated holes also with the correct part number from the AIM. All I know is that I have been media blasting brackets all day to figure out what to use. :smas h:
Well that’s interesting. The ones with the same part number as mine has the two sets of holes close together. What part number does your AIM say should be on a 69? That far left painted one looks like mine the most. Wonder if 69 were longer. Confusing for sure. Wonder if mine has been messed with as you can see someone kind of scalloped the end of mine to avoid interference with something.

Bill the first 2 pictures have the 795 & 796 ending numbers shown it the AIM. Now you see what I'm dealing with. Not hell bent on being original but if I have them I would like to use them.
Gentlemen, My company made these front bumper outer extensions for GM. The 68 and 69 extensions are the same. For some dumb reason, GM made them end a little lower than the outer bumper bolt holes. So 68 and 69 have an offset bracket that goes between the bumper hole and the end of the extension or brace. In 70-72 the arms bend up more and end at the same height as the outer bumper bolt hole. The smaller extension for them is "U" shaped. If you bump a 68-69 front end, the front bumper will bend up after impact because of the offset. It is easier to get at the 68-69 bolts to tighten them up.
Roger, in your photo the left hand painted brace is probably for a 73-74. That is why the end has extra holes to bolt to the rubber bumper.
The next pair look like they should be 68-69 ones. Note the very slight bend in them.
The third pair... I don't know. We never made any that had two elongated holes back to back like that, that I remember.
The last pair look like they could be for the 70-72's. See how they have a steeper bend in them than the second pair.
I do know that there were a bunch of different braces made due to different types of front bumpers. Also someone is reproducing these braces and they could be different than OEM, I don't know.
I hope that this helps you guys. Roger, I have a couple of these that I got from work and could look at the numbers on them and give you measurements if you need them. Sometimes GM changed the numbers on parts. I know most of the parts that we made had the trade mark circle with MTD in it, but later on some did not.

Hi Lou, thank you for that great information. I know you helped me and I would bet a few others. I forgot that you worked at MTD and was not sure if you made those. You are exactly right there are MTD markings in a circle on the set you mention. I now have to check the pieces that bolt into the tip to see the difference. This deserves a phone call. I will talk to you as soon as I check the parts.
Thank You
Roger

I just checked my 68 and 69 AIM's. The 3958795 and 3958796 brace are correct for 1969. The 68's have a different number 3914257 and 3914258. The AIM diagram even has the 68 shape slightly different to me. Both years use the same extension 3922077 and 3922078 that bolts to the end.
Roger, those two braces that have the two holes next to each other, have the original 69 number and the newer simplified GM number 391425. That has to be a "service part" replacement that we probably made. Do they have the MTD (Modern Tool & Die) circle? Lou.
So my 69 has the 68 part numbers. My car is in the 11000 VIN range. Wonder if they could have been originally on my car. Thanks for all your info Lou. Going to check my bolt on extensions for a part number.
The 1968 and 1969 front frame extensions and bumper braces are not the same. The basic design is the same but the upper front hole is spaced different on the parts. The attached picture of the front frame extension shows the difference in the hole spacing.
I got this picture off of Ebay. You can see someone added the extra hole to make it work on the other year. GM actually made service parts for the front frame extension with both hole spacing's for a while.
The front bumper braces had to have a hole spacing that matched. On your bumper brace with the two slots it looks as if someone has modified it to work with the other year hole spacing.
Thanks John, I noticed that they also have the MTD in a circle so like Lou mentioned they were probably GM over the counter parts. Also looks like the piece on the 2 slotted brackets is getting awfully thin!
Thank You for your time as well as all the other members.
I just noticed Navy08's thread and the picture of a new brace saying 68-72. I want to warn potential buyers that GM quit having us make the 68-69 brace and only sold the 70-72 one's as a replacement. You also have to buy the 70-72 extensions to make them work.
This was common GM practice to make one size fit all to reduce listing and making repair parts.
They did this with the front grill guards also, selling a 70-72 guard without the extra 70-72 piece welded on. But it did not have the 68-69 raised inner part to match the cast chrome plated lower grille piece.
69TTop502 Do your 68 number braces have the MTD circle logo on them? Lou.
