Make Those Long Hauls Comfortable
There is nothing like getting out on the open road and taking a trip in your hot rod. Multi-state events where you are behind the wheel for several hours at a time mean your driving position must be one of comfort and control. Having the seat positioned just right, a tilt steering column, and proper pedal placement are all key to enjoying the ride and not arrive at your destination feeling like a pretzel.
Tilt steering columns are an easy upgrade, and we offer everything you would need to make that upgrade to your vehicle. Same goes for our huge selection of gas and brake pedal assemblies. So, when it comes to getting your aftermarket seats just right in your early hot rod, don't sweat it, we have you covered there too with our Universal Seat Mount and Slider Kit.
Universal Seat Mount Works Best With Flat Floors But Can Be Modified to Fit
With a mounting bolt pattern of 14-1/4-inches x 18-inches center-to-center the steel tube frame in our Universal Seat Mount and Slider Kit will fit most any flat floor of an early pre-war car or pickup truck. Order a pair of these and update your classic ’40s or ’50s bench seat ride to a pair of buckets, providing more support and comfort and room to add a center console!
Of course, if your ride’s floor is not totally flat a little cutting and welding will allow our steel tube frame to conform to just about anything. Shorten the legs or lengthen the legs as needed to get just the right seat position you are looking for. On flat floor installations our kit should work as delivered with little to no modifications. However, some customers may feel the seat height is too tall, and in these instances cutting the universal seat mounting frame down to your desired working height will be your best course of action for a comfortable driving position.
We include all hardware to mount the seat sliders and seat mounting flanges to the steel frame and even include 1/2-inch steel spacers for clearance between the seat and sliders so that the slider mechanisms work properly without binding. This provides a 7-inch overall height to the assembly, which is not usually a problem in early hot rods or pickup trucks with a completely flat floor. However, you will need your own seat mounting hardware (often included with the seat) and hardware to mount the steel tube frame to your floor.
Includes All Major Components to Mount Your Bucket Seat
Our Universal Seat Mount and Slider Kit begins with our universal seat brackets built from a 1-inch OD round tube steel frame with .813-inch OD cross bars for strength and support. These steel tube frame bucket seat mounting brackets are 5 inches tall and are designed for early hot rods and pickup trucks with a low and flat floor pan area, unlike later cars of the ’60s and ’70s that utilized welded-in-place automotive seat risers. If your vehicle’s floor is not completely flat the frame can be cut and modified/welded to fit your exact needs.
Included is a seat slider kit which features a pair of ball-bearing supported seat sliders with mounting hardware. These universal seat sliders allow up to 7 inches of seat movement to give you that Goldilocks feeling of sitting just right; not too close, or not too far from the steering wheel and pedals. Seat sliders are the perfect upgrade for easier rear seat access as well. The adjustable seat sliders feature individual locks for each side controlled by a single hand lever, making seat adjustments quick and easy without that “seat wiggle” a single locking seat sider can cause. They bolt directly to our bucket seat mounting brackets.
Our Universal Seat Mount and Slider Kit also includes a pair of universal seat mounting plates to aid in facilitating the seat to slider/frame mounting. Depending upon the seat used there may be some drilling required of the plates or possibly additional mounting hardware required, so it is best to mock everything up on your workbench before mounting the steel frame base in your ride. If you are looking for universal seat mounting kit with brackets and sliders to mount your aftermarket bucket seats into an early hot rod with a flat floor, this is the kit for you.

Customers highlight our product's versatility, as the universal seat brackets have been successfully used in various vehicle models, from 1955 F100 to 1972 bronco and '40 ford coupe. While modifications were needed in some cases due to its universal feature, customers generally found it manageable. Sturdiness, quality, affordability, and perfectly fitting on different cars stood out in reviews. The height was also praised. Some users expressed an issue with the absence of instructions and required hardware adjustments, though most were able to resolve this minor setback. A few users had a challenge with using the bracket for a bench seat due its complexity. Overall, for their price and quality, customers strongly recommend these brackets, with many stating they would buy this product again.

Excellent Fit
Used these in my 1939 Chevy Business Coupe to adapt some late model corvette seats. Minor mod were required to cradle the seats just right but if I decide to go a different route later, these will be easily adapted once again.

Not what i needed for my application
I was told that i would have to use this kit to install the Scat Procar Sportsman 1605 in my 64 Nova. The conversion kit not only made the seat sit too high but left no room to get in and out of car. Seemed there were lots of extra parts that were not needed and there was not any instructions for assembly. At 5'8" tall my head was into the head liner while sitting in the seat. I pulled the original hardware out that came with the seat and was able to use it instead with minimal fabrication. ( made angle brackets and drilled holes to match seat structure out of old bed frame rails i keeep around the shop for purposes like this.) Original hardware that comes with the seat is much better for the Nova. Making 4 brackets for each seat is much easier than dealing with the after market kit. the seat slide assembly works great and the install was a breeze after figuring out the best method. Seat # 2 went in in an hour.

I needed seat rails for a bench seat. This as for a bucket seat, so I extended the middle brace tubes and the release cable. I also cut the legs off 2" to lower it. It works perfect. Even though I didn't use this for exactly what it was designed for, it was built good enough to modify. The sliding mechanism and lock works great. The pic is before I lowered it 2 inches.

I'm using on a 36 Chevy master coupe, the height is great the only disadvantage is that you need to mark and drill new holes to bolt seats down properly other than that they are great
