I am considering mounting my bumpers without the rubber/aluminum rub strip.  I will use polished stainless carriage or button head bolts thru the bumper.  The attached pic is a car with a similar mount.  My question concerns the bolts that are at the end of the bumper.  Is this a common way to mount?  Are these bolts needed for extra support?  On typical mounts they would not be noticeable because they would be covered.

 

This car was sold by South Atlanta Motorsports and they said it was built by Vintage Speedsters.  Is it common to have these bolts at the ends of the bumper?

I think that "trimless" bumper style works best when there is no side trim at all, more outlaw, stripped down looking. Note the picture you posted shows a car without the rocker panel trim. I'd lose the rest of the trim up top as well, but that is just my useless opinion.

 

That bolt attaches the end of the bumper to another bracket, I believe. I noted that Tom Boney's newer Vintage had that same bumper bracket system, whereas my 2002 Vintage lacks that extra bracket at each end. If I would have had it, it might have saved my bumper from getting broken last summer.

 

I like the look.

James;

I have a CMC so I don't know if this holds true for your VS. The last bolt in mine holds the chrome/rubber trim piece in place, probably required due to the large bend in the bumper (same on the passenger side). Take care in bolt material selection, galvanized metal does not take paint very well.

Thanks. I don't see them on the Vintage site.

And I agree, Wolfgang.  My intention is just to stiffen up the ends to eliminate any potential vibration or sag.  To make "real" bumpers would require some more steel! 

 

My VS was delivered last Nov and there are no brackets, just the bolt going thru a rubber cushion and the body.  I'm sure its just to dampen vibrations that might crack the bumper. With fiberglas bumpers there isn't much protection any way so I don't think outer brackets even if they went to the frame would do much.  You could use some large flat headed bolts that my bolt house calls elevator bolts and bond them to the back of the bumper with kitty hair or glass mat and use some shock absorber bushings to cushion them against the body. This would do the same thing as the car above without the bolt head going thru the bumper.  It might actually be stronger as I think eventually the head of the fastener will crack the paint around it.

Hi All,

 

i just mounted bumpers this past fall.  I used a 'L' bracket attached to the back of the bumper front and rear with carriage bolts as mentioned.  There is no need to put bolts on the end.  A fiberglass bumper really isn't that heavy after all.  I did use deco strips but I did mount the bumpers temporarily without the deco strip to align properly.  I kinda liked the clean look of it but wanted a more classic look. 

I always go by the notion that the least amount of holes drilled through something the better.  Four bolts is plenty.  If you don't already have brackets you can make some from bar stock from Home Depot and make them as long or short as you like.

good luck.

Frank
