SS Bumper bolts

I came across an article from Hot Rod magazine about SS verification. One of the pics was showing the bumper bolts were different on a Malibu vs a Chevelle SS. I have a question for those that have a verified 70 SS. Are the bumper bolts flat looking or do they have a peaked look? Hot Rod says the flat ones were SS and the peaked were Malibu, but yet in the pics they showed it would be backwards from what they are saying. That's why I'm asking the question

Re: SS Bumper bolts

I'm pretty sure that all Chevelles have the same bumper bolts, SS or not...

Re: SS Bumper bolts

I noticed the old bumper bolts on my 71 Malibu seemed to be flat on the top of the crown so I replaced them with the same type.

Re: SS Bumper bolts

I am going out on a limb here and thinking GM had a few suppliers for bumper bolts and I think they are the same for a lot of cars and trucks. and each supplier might have a slightly different tooling that wears at different rates and would produce a different shape

Re: SS Bumper bolts

No its true about SS cars having different bumper bolts. They were made of higher strength steel because the SS cars had potential to gain higher speeds so if they hit something the bumpers wouldnt fly off because of the higher strength steel.

Seriously, I replaced my original (true SS car) bumper hardware several years ago when I had my original bumpers rechromed. I replaced them with hardware from AMK products and they were exactly the same as the originals. I expect different hardware suppliers to be a much more reasonable explanation.

I call BS to Hot Rod and their 'expert' scribbler.

I sincerely doubt that the dedicated & notorious bean counters at GM would have approved of different bumper bolts for Super Sports.

Different suppliers as noted above seems more likely.

Re: SS Bumper bolts

I don't believe there was a difference in the shape of the crown of the head either between a SS or Malibu. I looked on AMK's site and the bumper bolt kit they show for a Chevelle looks to have the flat on the crown but it dosen't specify it's for a SS or a Malibu. Sure it's not April 1st.

Re: SS Bumper bolts

I sent Patrick a message and we will see what he has to say I guess. It does seem like it would not have been cost effective for two different bolts. Maybe it depends on what plant the car was assembled. We will see.

Re: SS Bumper bolts

Ok to settle this here is word for word from Patrick. "I wrote the article. To clarify, all 70 Chevelles had the 1 in nearly flat stainless cap bumper bolts. The tall version isnít correct"

Re: SS Bumper bolts

If your down to the bumper bolts, to convince yourself or other people your car is an SS, your dreaming. Just enjoy the car that you have.

The article was misleading and inferring the SS had different bolts. I have never heard of that and was wondering why GM would do something not cost efficient. It might be good information for a restorer to make sure the bumper bolts are correct but I could care less. Bolts don't make a car!
