Other mirrors that use same holes as sports mirrors

[ctsandb]

Ok, I've spent the day searching through the archives to see if there are other mirrors that use the same mounting holes as the 71-72 sports mirrors. I don't want to add more holes to my doors. I currently have some large west coast style mirrors but it originally had sports mirrors and want to move to something like that. I would like to look at some other options that are a little cheaper than sports mirrors but only if they use the original mounting holes. Options? Or do I just need to bite the bullet and shell out the $ for the sports mirrors.

Thanks!
