As many of you have read, I've been working on a 1968 Coupe DeVille for a friend. The definitive source for Weatherstripping seems to be RubberTheRightWay (http://www.rubbertherightway.com/) out of San Diego. They have an eBay Store (http://stores.ebay.com/Rubber-The-Right-Way-Classic-Auto) in addition to their website (http://www.rubbertherightway.com/). From my comparisons, the eBay prices are a little cheaper but the eBay shipping tends to be a little more and they do not combine eBay shipping. For me, here in So Cal, across the board it is cheaper to order from the website.

One of the items I was going to order was the TRIM piece that attaches to the body under the trunk lid and fills the gap from the body to the bumper (see pix below).

As you can see, the original piece was made of a composite material and painted black and looked like crapola.

But the replacement kit was $30 (http://www.rubbertherightway.com/1968-cadillac-restoration-parts-rear-35553-prd1.htm).

Really? for a couple of cut pieces of light weight composite? My friend refused to pay $30 for that and came up with a brilliant substitute; At the local Home Depot store, he picked up two strips of black rubber baseboard molding such as would be used in a kitchen or bath for about $2/piece. The UPC is 6 62756 37075 4.

Very simply, I removed the old trim and set it on the back of the rubber baseboard strip. Note that the baseboard strip has a 'top' and a 'bottom'. The 'top' is the side with the 'beveled' edge, while the bottom has a slight 'L' shape (wall to floor)... For these purposes, I essentially cut upside down so that the 'beveled', finished edge lies on the bumper while the cut edge butts up against the body. I used masking tape to mark the ends. I then took a metal straight edge and new razor blade and cut the lines. Then I drilled pilot holes where the screws would be mounting it to the body. Simple. Here are some pictures of the end result.

1. The original trim overlaps in the center but at the ends closest to the tail lights leaves a gap of an inch or so. If you use the original trim as a template, measure the gap space BEFORE removing the original trim and ADD the difference extending the template for cutting the new piece. I found it much more aesthetically pleasing and fully functional to extend the new piece to the edges where the body starts to curve.
2. On the first piece, I used the old trim to mark and drill the pilot holes for mounting, then found myself needing to re-drill / adjust those holes slightly. What works much better (as I did on the second piece) is to use a drill bit smaller than the body mounting hole. Put the newly cut trim in place (Position in the center first, lining up the beveled ends so that the created "V" is centered to the bumper... don't worry if the first piece extends beyond that center, you can go back and trim it later). Starting at the center, feel for the body hole and drill a pilot hole into the rubber in the EXACT spot where it will mount. Be sure as you move from hole to hole you have the rubber stretched flat so that it does not bunch up in between mounting screws. You will see what I mean when you get there.
3. The overlap on the original pieces is excsessive. The center mounting screw goes through both rubber pieces at the center and into the mounting hole. After I finished mounting the second piece, I went back and undid the center screw. Using a very sharp pair of scissors, I trimmed each piece so that the overlap was minimal but sufficient, and that the 'beveled', finished edge made a perfect "V" in line and centered to the "V" on the bumper.

$4 cost. Very little time spent in cutting the pieces. No waiting on shipping or delivery. IMHO, a better finish than the 'kit' online provides and fills the gap further on the ends. No Brainer. Good Luck.

Good idea! definitively better and cheaper than original. Thanks :)

that looks great...almost no way to tell that that's not factory.

good job, thanks for sharing that idea :)

Great Job!

Can anyone tell me if a 69 is supposed to have trim like this? Mine simply has a gap between the trunk lid and bumper. It appears perhaps a previous owner put some black electrical tape in there so there isn't a strip of body color between the two.

No trim like this in my 69. Canīt remember if there are any holes to attach it and I wonīt see the car until next week. :hmm:

Rubbertheright way is THE place, everything I got from them was far cheaper than any other place, they will always very helpful and although the name says rubber, but they have lots of other spared.

Positively 69 models did not use this kind of trim. Iīve checked in other pics.

RE '69 & holes to fit...

On the '68, the 'ledge' where the holes are drops down / recesses a bit from the trunk body so that when the filler is installed, it is flush. For fitting and mounting, this is great because it gives a perfectly straight edge to bump up against. And, the molding I used in the pix above had a thickness that matched.

BTW, RubberTheRightWay is a GREAT shop and I just ordered a butt load of items from them. But some things are a bit over priced for what you get and this was one of them.

BTW, another site which had a lot of filler and weatherstripping types of items is http://www.usapartssupply.com who's
online catalog can be found here (http://www.usapartssupply.com/uploads/USA%20PARTS%201949%20-1970%20Cadillac%20Catalog.pdf).

NOTE - I've just come accross this vendor for the very first time. Their catalogue seems to have everything including very hard to find parts. Some prices are a little high while other prices are competitive. One thing I love about this catalogue is that they use all the original part numbers correlating with the original Cadillac Parts Catalog found here (http://www.modifiedcadillac.org/documents/Shop_Manuals_and_Illus_Catalogs/Parts%20Illus%20Catalog%20thru%201970/).

Thanks, I already knew, and itīs right. They have most of parts though prices are not the cheapest. Their catalogue has been often a help when trying to find the correct part.

Thanks for sharing this idea! Great write up and pictures. I did this yesterday and it turned out looking better than original. The new material is very soft and compliant- I hope it stays that way.
