CArl,Thanks for the response! I guess my preference would be to NOT deal with fabbing an adapter, and taking out the rain visor, etc.
If you have a vent window assy from a 56 Sunliner that you would be willing to part with, Id much rather get the "right" part than try to adapt one from a '55. Are the sunliner ones unique tot he convertible? I always thought they were.
I need the one for the passenger side; Im not worried about it needing replating; the one from teh 55 needs that as well....
If you want, you can email me at rongrove(at)comcast.net Please let me know if you have the right part. THANK YOU!
