I believe its comes complete as part of the cowling
There's a good chance that it's very similar to other cars so if you go to a scrap yard you should be able to find one similar, however you would want to find a slightly longer one and trim it down just in case
Yeah, i am leaning more towards that it is a part of the cowl top part #. some pictures i see dont have it as part of it some do...the FSM does not seem to list anything in window trim for the bottom. i guess ill see and order the cowling.
