I have been putting up with scratching the door sills of my 89 S2 ever since I bought it and it's been driving me crazy! Every time I opened the door there they were, SCRATCHES! I would touch up and re-touch up and then I had an idea. So, I thought I would pass it on to anyone else who suffers from the same problem.
I bought regular 911 threshold strips from Pelican and cut them to fit the application.
Part #911-551-619-00-M260 Left & #911-551-620-00-M260 Right.
The cutting involves a sharp box knife or one of those plastic disposable types where one can trim the blade as it gets dull. I found the thin blade worked best. You will also need masking tape, a straight edge about 36”long min and about an hours worth of time. Strong fingers help a lot to!
Lay the threshold strip flat on a 2x6 on saw horses with the rolled edge over the edge of the 2x6. Next I used a roll of drywall tape to make a template from the door sill of the car. Lay the template down over the threshold strip with a straight edge on top of both and then clamp them to the 2x6. Set the metal straight edge in about 3/16 in from the long edge without the over hang. Shave about 3/16" off the long side. Position a smaller straight edge to cut the angled end.
I think that about does it. Any questions send me an email I’ll try to help you if I can.
