1977 308 GTB US Pushing the front bumper back (in) to Euro standards. Does anyone remember the thread for doing that? I remember something about puncturing the gas section. Tim
Remove the bumper shock. Drill a 1/4 " hole in the chamber. (use a press if you have one) Drain all the oil Completely clean and grind the area free of any rust, debris or oil. Push in the shock to the desired depth. (about 2") Weld the shock completely around to keep it in place. Reassemble shock to bumper While returning the bumper to it's home, be careful of the horns. I had to move mine into a vertical position.
I didn't weld mine when I did it to the GT4. I tapped and used a set screw in the original position, and the compressed position. (Two hole positions). That way, IF, you ever wanted to go back for a concours event or something original, you could do so. I think the thread I had started was EuroUS Bumper Mod, or something like that.
