I searched the forums a bit, I can't seem to locate. Does anyone know a thread, or the size of speaker I can fit? I thought in the past I read it has a spacer for smaller round vs oval speakers, you can go either way?

Thanks for any help.

 

Hope this helps, from my 968:













You can see I drilled new holes for the speaker mount that are slightly different from the OEM.

 

This is great!
Thank you! Now to find the cheapest place to get the continental radio.
