The only issue I have with the bug mirrors is they stick up at a 30 degree angle like mickey ears.
(OK, maybe 15 degree angle, not that bad, but still not kosher)
I picked up a pair of mirrors for a Ghia awhile back, they are perfect angle, except the mount bits are the wrong size for a T3.
(and the mount parts were borked to the point one wouldn't even have worked on a Ghia)
Seems like every manufacturer uses a totally incompatible setup, I have a drivers mirror sorta rigged & working ~properly, but I had to drill out the passenger side mount to fit the early mirrors.... dumbass.
I have a OG T3 mirror on drivers side and had the T3 mirror on passenger side--- perfect mirror image.
These guys actually MAKE T3 late style mirrors, (essentially Ghia w/T1 mounts) they just don't realize it or refuse to sell them in that configuration for unknown reasons. An old saw is to assume stupidity vs. malice, so I'll go with that.
I may further harass CIP1, he guys I have spoken to are VW nuts, they might be able to come up with something, perhaps they source from one mirror vendor, and the bits are compatible, you never know.
Bus mirrors screw right on and adjust to any angle, unfortunately I'd have to always tow a trailer or look even more of a total dork.
Sadly the part that screws in is also not compatible with the T3/Ghia head/collet bit.
