Trim strip seat

The original seat was in pretty bad shape, a big hole in the vinyl cover and the seat pan was rusted through in some spots.

 Luckily I found a nice replacement but this one was without the stainless steel trim strip. The strips slide over  aluminium rivets that go through the metal seat pan and are fastened by clips on the inside of the pan.

I carefully pried off the clips so I could reuse them later. When the rivets are coming loose just slide the trim till the round opening reaches the rivet head and take it off.

At first I thought one of the short strips was a bit bent but after checking pics in the official sales brochure I found out the right side strip is indeed different from the left strip.

Now the hardest part, measuring and locating the right spots for the rivets in the new seat. Most important thing is that the holes are at the same height (if you want the strips to be nicely horizontal). With a 3.5 mm drill I drilled the holes from the inside of the seat pan. Drill with very low rpm's so you won't damage/burn the vinyl cover.

Don't put the clips on straight away but wait till the trim strip is exactly in the right spot, it's really hard to peel 'm off again..

I also re-used the original hinges from the old seat because they were a better fit than the new ones.
