GM car cover/'vert spoiler question

[United_727]

I am looking to get a new car cover in the spring,as the elastic on mine is shot. I like the look of the GM accessory one,but I was wondering how good it will stay on in the wind? Does it have lower holes for a cable? My other one I had to attach the front and rear parts of the cover with bungie cords.

Next,I was thinking to getting a factory convertible spoiler to replace the factory RS one on mine. I think I read on here that the holes in the decklid are identical. I would assume that aftermarket 'vert spoilers would have the same bolt pattern? The factory 'vert spoiler is a little pricy and has to be painted.

Thanks.

Be carefull, one member here bought a spoiler and said the bolt pattern was way off. I'd messure the space between the Bolts and verify with the seller.
