What do you do with the energy absorbing mount of the front bumper? It seems like when two cars get together it rips one side loose and they spend quite a while getting the other side ripped loose, and end up laps behind. I was thinking of welding angle between the plates on the frame and the bumper or cutting a peice of pipe in half and welding it between the plates.
Thanks

i took mine clear out. front end weight. took 2 plates of 1/4" steel and welded a pipe in between them. welded one to the frame and bolted the other one up to the bumper. find a aluminum bumper if you can.

i always look at it this way it's always better to have something that will give to absorb the impact i always use the stock ones and cap the bumpers to the fenders with metal. i don't like the idea of my bumper being a part of the frame i know there were a couple nites that if mine was welded solid i wouldn't have a front end left on my car but the bumper tore away and took the force with it

Racer 17 J is right. The bumpers should absorb impact even to the point of being sacrificed. There are several ways to accomplish this, using the stock shock type or by designing bumpers to crush easier than the chassis. A crushable bumper means a straight chassis. SLEEPY

I have run the energy absorbing type on my 76 Monte for many races and saved the frame many times...I weld in short lenghts of chain as a stop to keep them from pulling apart...

Just a warning.. Id be carefull welding onto the asorbers some of them are gas charged like shocks and can explode. A colapsable bumper is the way to go but we always removed the stock type asorbers and built ours with a piece of 2 in sqaure tubing welded to the out side of the horn with a piece of 1 3/4 slid inside it that mounted to the bumper.We used one 3/8 grade 5 bolt through the 2 and 1 3/4 tubing as a shear pin and also gave the bars an up angle to the bumper to help absorb an impact
