Do I need to order one or two?

From the looks of the picture, it seems that it'd be two-piece?

Mine's missing so don't know how much to order.

But it LOOKs like it's only one-piece???

The rubber bumper strip is one piece, but the metal pieces that are riveted to the bumper and used to install the rubber strip are two piece items in order to provide room for that chrome metal strip that joins the two bumper halves together. The metal support pieces come flat and have to be molded the bumper.

So are you saying, item #21 in the below pic, I need TWO of? Or do you think if I ordered it, it'd come in two pieces?

So the metal strips are riveted to the bumper? Can one use screws or have to use pop rivets?
 
Why wouldn't you wanna use rivets? I recently rebuilt my front and rear bumper and rivets worked just fine. Also, I fidn't have to use any sort of grease to get the new rubber strip on. I simply started in the center and worked my way out, continuously flexing open the rubber strip. Went very fast!
 
My 3 cents

OK, so I did the conversion to '72 bumpers on my 74 and when I got the bumpers I had lots of work to do on them. The rear rubber strip is indeed 1 (one) piece, and in my case, the strips must have been removed by a PPPPO and they were actually held on by strips of license plates that someone had cut up and fashioned into 2 inch long retainers and then they used screws with the heads flattened, or shaped so they would not protrude from the make shift channel, so I, not knowing, got some steel strips and formed a channel in them, made the strips a little longer and put the strips (with the screws) into the runner piece and then attached them with nuts and little lock washers. It took a long time but was not really difficult. I thought that was the way it should be done and it came out perfect. 3 coupes later I realized what a dummy I was (am) and now just buy the strips, drill the holes, use proper size pop rivets and put them on the easy way- as described in a recent thread. One note though, when you drill the holes- which takes a little time as they need to be measured after bending them to line up with the bumper- keep the strip perfectly centered (top to bottom) or when you put the rubber strip on there will be a gap on either the top or bottom- Please don't ask me how I know!

It's a fun, low tech job that looks really great when finished,

Good luck!
 
Paint the strips first, they will last longer and the paint will help with slipping the rubber on.
 
I didn't find US Pop rivets in the right size, so I bought metric Pop rivets at Bauhaus the last time I was in Germany.
 
Peter (or anyone else), where do you buy the strips or "holders" as the parts diagram calls them?

Part 51121811045 shows up as NLA on getbmwparts.com. I need to get both front and rear ones.

Thank you.
 
I'm pretty sure I got mine over the summer from Ben at La Jolla Independent. I believe Peter bought the Coupeguy stainless set, which is more expensive.
 
@Ohmess: Thank you. I did fire an email to Carl.

@deQuincey: Brilliant! Of course... why not ? No one can see that, the only important part is that it holds the rubber. Now the obvious question is where did you find that kind of metal blank? Is it stainless?

@Bmachine: that is an original BMW part, just like the old rusty one that can be seen in the first pics, it is galvanised Steel.
i did this in 2009, i recall i bought it from walloth&nesch
regards
 
I bought mine from ECSTuning, but Coupeguy.com has stainless steel versions for same price if not cheaper.

[FONT=Geneva, Arial, Helvetica, san-serif]304 Stainless Steel formed impact retainer strips which you simply bend to fit the bumper contour and drill to pop rivet to your bumper just like the factory parts, but will NEVER rust. If your rubber impact bumper pieces are drooping, falling off or missing, these have probably rusted away. The factory parts rust very quickly as do other repro replacement strips which are just pre galvanized steel which will rust as well. These parts will never rust, and even though they are hidden in use, they still look great. Fronts 26" long - $60/pair Rears 44" long - $90/pair or $140/set of four.[/FONT]
 
Great tip. Thanks teahead.

I'm curious to find out if there might be a generic aluminium profile that might fit this. Although the curb might flatten it...
