Bumper Rub Stips

Post by 76 Malibu on Wed Nov 19, 2014 9:57 am

The front rub strip on my bumper was damaged a while ago. Is there anyone out there who makes a replacement? If not, is there any way to repair them? Mine is cracked right at the corner and it makes my other nice bumper look terrible.

I have looked in the past for these, but never found anything even remotely close in 30 years. You will likely have to win the NOS lottery, and they will probably cost a fortune. If someone does start repopping them, though, post a link -- I'd love to get a set.

Probably not -- look at the difference in our front bumpers in just our avatars. I know I was never able to locate any for the Monte. I just assumed it would be the same story for all G3's, since we have a hard enough time just finding stuff like sheet metal.

I would assume they aren't the same for all years. I would prefer bumpers without them, but it seems like just a waste to get rid of an original bumper with good chrome because of a rubber strip.

If anyone else has any sources or ideas on how to repair them, please chime in.

Maybe use some epoxy and then paint with a vynil dye?

Are you just trying to fill a crack? Or, are the edges either side of the crack lifting away from the bumper? If the latter is the case, I don't see any practical way to secure them down. I could keep an eye out for a good used one...but, I'm guessing it requires removal of the bumper to access most of the nuts behind it? Can be a lot of work if the nuts are rusty.

The damage is right on the corner. Right now, it just has some black duct tape carefully applied to keep it together. It's not too noticeable unless you look closely.

I think a bumper with holes for the rubber strip could be used OK if the holes had stainless bumper bolts put in them, or other round head bolts etc. Some place like McMaster-Carr would possibly have something in smaller size, to match the holes..
Not using a bumper that is in nice condition seems a shame. The cost of re-chrome is getting crazy these days...

I'm probably in the worst scenario in this particular case.

The previous owner at some point the strips ripped at the corners and the just NAILED in back into the bumper. The nails were, of course, not stainless steal or anything so they rusted and broke, leaving the strip on one side flapping in the breeze, while the pure rust nail IN the bumper.

I'd love a repop if they'd make it.

X3....the strips on my Elco aren't the best either. I added a couple more screws to hold one of them on. I counter-bored the rubber so the heads were recessed, and covered the holes flush, with 3M black weather strip cement.

I checked my photos, I don't have one showing the damage clearly. The car is in storage now, so I can't get a new shot right now.

Does anyone know if I removed the rub strip if these bumpers for the rub strip and non-rubstrip cars are the same? I saw some pics of cars without the rub strip and chrome bole heads and they look alright. I am just not sure if the bumper has the "groove" or slot that the rub strip sits in. Where can I get chrome bumper bolts?

This car looks fine without the rub strip:

Bumpers will have the same shape with or without the rub strip. However, you will have at least twice as many holes (my spare rear bumper rub strip has 13 mtg studs) in the bumper to accomodate the mtg studs for the rub strip. They could be filled with bumper bolts that can easily be found online...but, it's going to look a little busy across the bumper. Manual shows them to be 3/8"-16 x 1" lg. btw.

Didn't Foose do something with an Elky bumper? I seem to remember them cutting down a back bumper and filling those holes in.

Probably shaved the bolt heads. Basically cut off the round head & weld the square part to the bumper. It would then need rechromed or painted.

I opted for the extra carriage bolts when I swapped to a new rear bumper, and I'm planning on doing the same for the front. The holes are also elongated, so the bolt heads will need to be about 1/8" larger than normal to cover the gap. I thought it came out all right -- what do you guys think?

The 8 bolts don't look unnatural on your '73. But, a '77 will have something like 13. As I said, it could start to look a little busy with the extra bolts. On the other hand, is it really that big of a deal, anyway? Pull the strip and put the bolts in and see what you think.

Speaking of bolts, are the hardware store variety of carriage bolts stainless or chromed? Seems I remember years ago, when I needed to remove the Monte's bumpers, the factory originals had a chrome cap over the head of the bolt.

Typical hardware store carriage bolts will be galvanized or stainless, since their intended use is for building decks and other such outdoor structures with pressure treated wood that eats ordinary steel. The galvanized ones are dull and the stainless ones are shinier and more expensive.

The ones designed for cars, though, have a chrome cap over ordinary steel. I'm sure this was a way for the factory to save money over stainless, but chrome also holds up to the elements better than stainless. Over time the stainless will look dingy, and, depending on grade, may actually develop surface rust.

However, if your car doesn't see harsh conditions, the stainless should work okay -- they're just not as reflective as chrome.
