If you have the time and glass skills, you could make them one piece. I think someone posted pics on here a while ago about doing that. I didnt really see the need, they look good how they are.
I just had mine done like this. When I get the car back and have a chance I will take some pictures.
I went with FRP Bumper Fillers from a company called
Replica Plastics in Dothan, AL. There is allot of excess overlap on the rears, so you have plenty of room for error in trimming...to a point.
Originally, I bought a complete set from a vendor that uses
Danko Reproductions. To no fault of the vendor, the Danko came directly from Danko and they were cracked and very brittle. The body shop did not want to touch them as they've had problems in the past with other Danko pieces.
I found the Replica Plastics by chance, and they're only an hour away from me so I picked them up in person. I bought a complete set (even the nose piece). I'm not a body shop person by any means, but my friend and I really liked the Replica Plastics pieces allot more than the Danko pieces just from the quality and the overall way they feel when compared up against one another. The Replica Plastics pieces are a Fiber Resin Plastic mix with a flex agent and they are allot more flexible and lighter than the Danko pieces. They seem more rounded where they need to be and not as squared off as the Danko pieces and the straight lines are straighter. The body shop had their fiberglass guy blend the two pieces together and it came out very nice. I was really happy with the way they flow with the lines on the side, they matched up pretty good except for the passenger rear which is why I took the car back the day after I picked it up and they're making adjustments. The center (beneath the license plate) where they melded the two together was actually touching the underside of the top lip of the bumper and the vibrations caused it to dig into the newly painted fillers.
These are the pieces from Dothan Replica before I had them put on:
If you buy these from the same company I did you should see if they can send you pieces that are not pre-drilled as the holes they drilled aren't lined up that well and it will require you to make adjustments.
Again, I had mine professionally installed because I don't do body work.
Once I have the car back, I'll take pics. But I was really happy with how it came out. The fronts matched up really nice, and the rear driver side matched up really well too...I'm hoping they can make the adjustment for the rear passenger side but if not you'll see what I mean when I take the pics.
I've done a search of Dothan Replica's on both forums and I've only found one comment but it was a question of how they are and not a review. Their website says they have a lifetime warranty. The shop itself and the owner was very interesting to say the least.
