For those who have a Firm Feel steering adaptor...

Okay - you guys that have the adapter and say it fit fine - did it slip onto the box effortlessly or did you have to wiggle it on? Sounds like the latter - and that what I would have expected.

Here's what the box vendor said: "...It’s pretty unusual for input splines to get worn down on a steering box. Once the coupler is bolted on, the “peaks” of the splines shouldn’t have anything touching them, so it would take prolonged movement of a loose coupler to wear them down. In addition, we have had no returns or warranty replacements on this particular box over 125+ sales in the last two years."

I don't have another box to compare anything to. I threw a caliper on the OD of the input splines and got .719"

What I expect to happen is have each vendor point their finger at the other.
