At AVCRIG We've tried all the domestically available swivels for the Ford Transit. I like the construction of the swivel, very tight and not a lot of play like others. Shipping was fast and reliable, all good things.
There are a few things a potential buyer should know.
The hardware included with the kit is too long for the swivel to operate. So you'll have to go to the hardware store and source your own grade 8 hardware to replace what's included in the kit. The mounting holes on the place are slightly off so you'll also have to use a sizing bit to open them up a bit for a smooth installation. Also the hole in the center of the swivel is too tight to fit the wiring harness. This means you will need to cut and splice factory wires for your Ford, not ideal. Our model had manual seats, so this wasn't a huge issue (only two wires). If you have a power seat this would be more annoying.
None of this is a deal breaker for a professional installer, but a novice at home install may in for more than you feel comfortable with.
I gave this product four stars only because I can't give it 3.5 It does function as needed, but falls short on the details.
