Hey all, I ponied up and bought some fiberglass Euro bumpers and have been fooling around the brackets, and bracket desigins to correct the attitude of the rear bumper bolt mount which is off about 20 degrees. I designed a couple different brackets here but am unsure which may be best to use. The first bracket emloys 6 screw holes which will mount flush and two larger M10 threaded holes to house M10 studs which will be used to mount the bumper to the bracket on the rear of the car. The problem with this is there is not a lot of room for error should I mount the brackets and find I need to noodle with the left to right or small height issues. The second bracket is essentially the same as the first (looks very much like Detroit's he made!) but will house a M10 bolt which mounts flush to the rear of the bracket with only the threads sticking out. This leaves a little more room for error and general noodling should it be required. This is not as clean a setup as the other but it will work fine. These will probably be made with 5052 T6 aluminum. Oh and by the way, if anyone knows of a good machine shop to crank these out for me, let me know! The online machine shops I have been looking at are going to run a little over a 100 a pop if I just have two of these made! ouch Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
If I follow you, you're looking to correct the tilt of the bumper in the vertical plane. I'd use a male/female spacer that would have a "D" male profile, look at the seat tilt adjustment on bicycles. this would allow for tilt rotation in one axis in an infinite number of degrees. delrin would make a good material as well.
I have seen fasteners similar to what I think you are talking about in the Mcmaster carr catalog. They have a rounded under head bolt and seating washer that allows some degree of movement inside the head seating washer. Unfortuately, this is where a paper catalog comes in handy as you can quicky scan thru the pages and look at the pictures for something that you don't know what to name for a computer search. Doug
