I can't find the post for the person that responded to me.

I need the driver side rubber piece for an 87 Si. Really, I only
need the square endcap to it, its on the front side near
the front fender (the rear is angled piece). So even if you
had an unusable/bent piece for the door/door smashed etc,
I cand still use the square endcap.

Thanks. condorski@mindspring.com

Ok....here's what I did: i took the endcap off a spare fender thing, epoxied it to the door thing, used a dremel to shape it then used a little filler and sanded it to look right. Came out OK!
