Center spoiler welting??
 

Does the center spoiler get welting like the fender flairs on 74 models? If so, is it attached with staples on each end and a goo in between?

Center spoiler gets the welting. I don't remember how it attaches, if staples are involved or not. I'd say probably not, but I don't say that w/ 100% certaintly either.

I decided to add the welting as the spoiler must mesh with the fender flair and the parts book stated 'spoiler assy.' which meant there was another part included that was not hardware related. I added staples to each end to secure it and a light bead of adhesive in the welting.
