I have done a lot searching -- and their is even a few year old post here (https://www.miataturbo.net/suspensio...stalled-83274/), I don't know the ultimate remedy is/was?

I apparently cannot get the passenger side axle all the way in, nor now, take it out. My pictures of the axle look like what that old post had.

Any one that has installed these find a remedy?

Thanks in advance..

 

From V8R:
They appear to be completely installed. There is roughly 1/4-3/8" of the stub axle that is exposed past the seal surface

 

X2 normal, mine looks like that.

Reach out to Driveshaft shop if you have issues, they make the axles.
Recommend venting the boots if you plan to road race.
