(IMG:http://www.914world.com/bbs2/uploads_offsite/live.staticflickr.com-17027-1611179652.2.jpg) Finally got the front flares welded on, metal finished, and covered with a couple of coats of epoxy primer. Before I move on to welding up the rears I want to fit the fiberglass front bumper. What's the best way to fit the brackets to the bumper... 1. Mount the brackets to the car, and then epoxy the bumper to the brackets and just hold in place with tape until the epoxy sets? 2. Test mount the bumper, mark where the brackets should be, and then attach them to the bumper off the car? (Not sure if there's even clearance behind to do this.) 3. Some obvious way I'm too stupid to think of? I'm assuming two-part epoxy is the best way to attach the brackets to the bumper... although, after losing other car parts on I-405 I figure I should double check. |

If metal epoxy sticks poorly. If FRP then no problem. If they are metal you are going to need to do it with bolts. Have had to fiberglass an angle to the main part and then run bolts through the leg out. Nice looking job on the fender. |

They're basically u-shaped fiberglass brackets that you have to attach to the back of the bumper and then bolt into the stock bumper mount holes. Which reminds me, anyone know if I also need to use the rubber bone shaped piece that the stock steel bumpers mount through? |
