Relocate Your Seats with Year One’s Seat Relocation Brackets

It has been nearly fifty years since the last of the original Mopar muscle cars ran off the assembly lines. During those five decades, the generations of owners that followed the original purchasers have, statistically, become larger. By larger, we mean taller and, regrettably, heavier.

Our old Detroit iron does not have the seemingly infinite seat adjustability of a late-model Mopar. Because of the adjustability limitations, some enthusiasts cannot sit comfortably in the automobile. Luckily, Year One offers universal seat relocation brackets (part no. SB246) or a pair (part no. SB246P), to eliminate the fitment concern.

Above: The Year One seat relocation brackets allow the seat to be moved forward or rearward a maximum of 2-inches. The SB246 kit has four brackets to adjust a bench seat or one bucket seat.

The above scenario recently played out with the Pennsylvania College of Technology’s 1967 “Dyno Dart.” A student, enamored with the Dart, purchased one for himself sight unseen only to find himself unable to fit comfortably between the seat and the steering wheel.

To increase the room behind the steering wheel, he and some friends moved the seat frames rearward by drilling four holes in the floor pan. The hack job worked, but it left the bucket seat sitting askew due to the floor’s contour.


Above: The instruction sheet provides all the information necessary to install the brackets. 

If he had contacted Year One, he could have picked up the SB246, which has four relocation brackets and related hardware to attach to the seat frames. The set can be used on one front bucket seat or a bench seat. The offset design of the brackets allows for the forward or rearward movement of the seat by 1 ½- to 2-inches. In addition, the black powder-coated finished brackets can be mounted on or under the carpet, if a cleaner appearance is desired.

Above: If your Mopar has two bucket seats that need to be moved, Year One has the SB246P kit, which includes eight brackets to adjust both seats. 

The hardware to attach the relocation brackets to the floor is not included with the kit. Therefore, in some circumstances, additional hardware may be necessary to secure the seat. Also, the brackets may require minor modifications to fit the contours of the floor pan. Each kit comes with an instruction sheet to cover the installation process. If your Mopar has bucket seats, Year One sells a discounted B246P kit with eight brackets to relocate both bucket seats.

Above: The inspiration for the student was the Pennsylvania College of Technology’s “Dyno Dart.” The college’s dyno classes have rolled over 3K-miles on the odometer in the last ten years. The students added many of those miles during 8-second wide-open-throttle runs.

The Year One seat relocation brackets are available for A, B, and E-bodies and are sold under the same part numbers. So, click over to Year One’s website for four or eight brackets. With the relocation brackets installed, you will enjoy a more spacious, roomy interior and benefit from the improved interior ergonomics of a properly located and situated seat.
