[Too Many Projects]

I was drilling holes in my nos rear quarter for the wheel trim and recalled I want a rear antenna, which will, obviously, require another hole. Looking for suggestions on experience with replacements that are quality made and correct appearing.

I've looked at the Retro sound and HBC's sets. I have bought a "few" items from HBC that are proclaimed OEM and/or assembly line correct and been sorely disappointed that they are not. At the cost of the HBC unit, I am hesitant to go that route without others with experience offering their thoughts on it.
Same for the Retro Sound unit, or any other brands you guys have used.
Thanks SYC
