Default Crash bar behind a fiberglass bumper

I'm in the process of putting a glass bumper on my 75 TA. It's a street strip car so I'm definitely putting a crash bar of sorts in. It just got me to thinking how many other guys put something in just in case?

I still have steel bumpers so I dont know, but if you're going to Fiberglass to save weight, wouldn't the crash bar offset any weight savings?

Scott not in my case. The glass bumper with all the mounting hardware will be less than 5 pounds. I'm not sure what moly tubing weighs, especially since I don't know what size I'm going to use, but will have around 8ft, maybe, in the crash bar. And anyone that has picked up a 74–75 bumper will tell you that 50 pounds is being generous.

I starting using glass front bumpers in the 1970s on my GTOs and still do to this day. My daily primary driver, 72 GTO has had one for over 20 years. Have 100s of thousands of miles driving them with the glass nose. Have even been in some minor wrecks with them too. The glass bumpers are much easier to repair than the originals. Have never used any type of crash bar.
I enjoy better balance, braking, cornering with the battery in the trunk the that heavy Endura/rubber off the front of the car. www.facebook.com/PontiacHeaven

Where did you find a fiberglass bumper for a 74-75?

I got fed up with calling places that advertised them that didn't have them or never got back to me so i made my own mold. it didn't turn out too bad for my first time.

I would definitely entertain that thought. Right now I'm having some issues with the bumperettes. I haven't done a whole lot of fiberglass work so this is fairly new to me. When I get everything cast and see what the final product is that is when I will make the decision. The last thing I want to do is sell someone a product that im not happy with. So far I've thrown away one mold of the bumperettes and one casting. And of course the casting messed up my second mold. I have that fixed and starting on the second casting now. I'm sure I will get it all figured out though, sometimes I'm not sure if being hardheaded is a good trait or not Lol

Once I get further along I will post some pictures.
