manual outside mirror '69 Road Runner

Can anyone offer suggestions on the best place to get a new manual mirror for my '69 Road Runner? I'm nearing the end of my 20 years of the car being apart and my existing mirror won't match the rest of my new chrome. I'm seeing mirrors on ebay for $60.00 & $89.00 and then in the One big catalog they are $149.99. Is there really a difference? I don't mind spending more if there is. Any comments would be appreciated.

If the Penta Star on the outside of the mirror matters to you, I still have a few left.

I bought a set of chrome racing mirrors from PG Classics for my 71. I was really impressed by the fit and quality of their chrome and glass surface. No pentastar or 7 digit Mopar number if it matters to you.

Thanks for the replies. Michael you have a pm.
