87+ rear speaker covers

[turnpike]

I recently purchased the rear quarter interior from a 91 GT but it didn't come with speaker covers.

I picked up some speaker covers off ebay and when they arrived they didn't have the threaded posts on the back side for the speakers to attach to with small nuts. It looks as though it should have them and none of the plastic is broken. The plastic for the threaded post is still there.

Did 87+ speaker covers have the threaded posts on the back side? Or where the speakers attached with screws of some sort?

I would think you can take off the rear 1/4s in your car and bolt the speaker covers on with bolts your self and it will work just fine. Just drill out the posts and put bolts in. Unless the whoels are already in teh posts in which case just put bolts in.
