Driver's side is well built, but needs a little finesse to install
I'm just over 5' tall, so finding a short base like this to use with the swivel seat was perfect.
The base is very well made. It's solid, the welds are good, and the powder coating flawless.
While basic installation was quick and easy - just slide in and bolt down - my only issue is the emergency brake plate that is part of the driver's side assembly needs to be raised by roughly a 1/4" to put the holes back in the original vertical level as the original base. It took a significant amount of finesse to force the holes to align again, and I gave up trying to install the last bolt that's behind the brake lever plate. Hopefully 2 out of the 3 bolts will work well enough.
If it wasn't for this struggle, I'd give it a full 5 stars.

Easy to install
I replaced both the driver and passenger seat bases with the lowered units in combination with Sportscraft swivels. Very easy to install, just some taps with a rubber mallet to get the rear prongs to engage with the pins coming up from the floor. You have to do some trimming if you want to re-attach the plastic trim pieces on the sides, but it's not a big deal.

The base was easy to install, fit perfectly for the passenger side I was using it on. It was just the right amount of drop to match up to the swivel I was installing to maintain the stock seat height. Arrived well packaged and quickly.

Promaster Swivel Seats
I purchased both Swivel seat adapters and two low profile bases. Excellent products - very well made and now I'm about an inch lower then when i started - perfect for a tall man like me. I am very pleased!

Great for tall drivers
This lowered seat base is great for tall drivers. Easy to install and fit perfectly. You can still use the plastic side covers (and screws) by cutting about an 1.5 inches off the bottom of each cover and drilling pilot holes in the base as needed to align the cover as before. The tool box will still fit under the passenger seat, but the tray under the drivers seat will need to be secured somehow since the lowered base does not include the attachment bars as found on the original base.
