1968-91 Ford/Mercury | S6 Black Hub Adapter | STH1010BLK

Tried this on a 1988 F150 and had similar issues to Evan on the 1990 Bronco with the adapter hitting the steering column housing and turn signal cancel actuator well before full spline engagement (3/16-1/4 inch short of full engagement). Thought about milling it down, but there was not enough clearance for the horn clock rings if milling it down for full spline engagement, so I decided to return.

The single piece billet construction is far ahead of the other options out there as well as the horn clock rings being soldered from the back side and being completely smooth on the front. However, sadly it does not fit the 88 F150 with manual tilt column and I did not see a way to modify and retain the horn functionality in the wheel. Hopefully there will be a revised part in the future.

The quality and finish of this adapter is pretty good, but it required so many modifications to work, that it's comical. I ordered this adapter for a 1990 bronco, and about the only dimensions that were correct were the spline count and outside diameter of the adapter.
I had to mill over a quarter inch off of the back of the adapter to keep it from hitting the steering column when tightened down.
I had to use the dowel pins for the blinker cancel which mostly works, although the pins hit the cancel tabs whenever they pass them, even if the blinker isn't on.
The horn button will have to be relocated because the horn ring in the adapter had huge clearance issues and had to be removed in order for the adapter to fit. The horn ring would crash into the blinker switch before the wheel nut was even remotely tight.
Overall, this is a horribly engineered adapter, and you guys need to seriously rework it. I would return mine in a second if I hadn't modified it to work.

Shipped fast, looks great, part of a big project so not installed yet.
