Drive Shaft Adapter fitment question

[Rotopod]

When I went to mount the driveshaft adapter, I noticed that it does not seem to fit properly with the differential.

The diameter of the gold adapter plate is too big to fit inside of the flange of the differential input shaft.

The manual states:
"**There are two different Driveshaft adapters, one for center sections from automatic cars which is coated clear zinc.
The Driveshaft adapter for center sections from manual cars is coated yellow zinc."

Strangely the Silver/Clear coated adapter plate fits, but the Gold/Yellow does not fit.

I guess it might be possible that one of the flanges was finished in the wrong color. But not both...
What am I missing?

I cant see any reason not to use the Silver Adapter.

I had the same problem. Ordered the IRS option from F5, they also supplied the driveshaft and gold adapter as well. Gold adapter didn't fit in the IRS flange. Called them and they sent the silver one, it fit....

Use whichever fits regardless of color.

Confirmed. The only one I had was the silver one for my IRS setup and it fit nicely. The manual needs to be updated in a number of locations.

Thank you! I appreciate the feedback. Silver it is!
