Door Sill Plate Taxonomy/Classification

It looks to me like #1 and #2 sills projects inside the car to meet the carpet, while the aluminum sill plate projects toward the outside of the car, covering the rocker.  Therefore 2 pieces were used together.  How will that work with the IE offering?

 

Edit:  I think I understand now.  The IE extrusion will not cover as much interior sill as the original #1 or #2.  Carpet will tuck under new interior sill (hopefully).  The IE sill plate will also replace the aluminum sill plate # ..5225 as well.

 

 

I think you might be right. #225 must have been an option on the earlier cars with thin sill plates until the later cars rolled out with wider plastic ones.

We were just thinking out loud. what if we made one that both simultaneously projected into the car to cover the carpet like 1.5" and projected outside of the car to cover the rocker. All one piece, kinda like you picture but both pieces made as one.

My '71, with a build date of 2/3/71 has option #1.  

I suspect the dates crossing over in the ETK might be that option #1 continued on with the 1600/1600-2 while option #2 rolled out for the 2002 cars???

Having nothing better to do, I looked at the BMW Parts Book.

 

Sill cover 51 47 7 470 007 used up to model 71 (Mar '71)

Sill cover 51 47 1 808 680 used from model 71 Apr '71 to Mar '73 (shows several 'up to VIN xxxxxxx' which are Mar '73 build dates)

Sill cover 51 47 1 882 070 used from Apr '73 to end production (shows from same VIN as above)

Not likely. The differences many people attribute to 1600 vs. 2002 differences are almost always differences of date, not sub-model. By 1969, the 1600 and 2002 were very similar!

 

Best regards,

Thank you, Les, this makes sense. Well, except, perhaps, for the switchover to the latest style a few months before the square taillight appeared. So I’m guessing there must have been a material cost savings and BMW decided to roll it out ASAP! ?

Thanks and best regards,

I have #3 and they are trashed, so I would be good with any aftermarket option that was similar looking, assuming price isn't outrageous.

 

I would also say that #3 begs for some sort of design in the middle, maybe a replaceable plate so people have options - BMW, 2002, ///M, ///M2, etc.

Sold these to someone who was building a resto-mod Diana clone (at least I think that is what he said). 

 

Found at a huge sale up here in the great PNW. 

 

Decided they were not for my 74, and this person really really wanted them.

BMW currently sells the door gasket for #3 as the one for #2. They don’t work. Would be nice if someone came up with an alternative. I ended up using a generic self-adhesive gasket on my (early) ‘72 tii. My ‘73 tii donor car came with the wide sills, though.

 

Would definitely be interested in aluminum ones like on vintage Porsches.

I have a set of the aluminum door sill plates if needed for reference.

Is that so? To the naked eye they looked exactly the same to us. What is the difference?
