Show original supplier description
The OMP HC/783/S is a left-hand seat mount subframe specifically engineered for the Toyota Celica GT and ST models manufactured between 1994 and 1999. This subframe acts as a crucial intermediate component in the seat installation process. Once the HC/783/S is securely fixed to the car's floor, users will then need to attach compatible seat mounting brackets between the subframe and their chosen seat. OMP offers a full range of these seat fixing brackets to ensure proper fitment and compatibility. For identification purposes, OMP part numbers ending in 'S' denote the left-side (driver's side in most LHD markets) fitment, while 'D' indicates the right side. If a part number does not have a suffix, it signifies a non-sided subframe that can be used on either the left or right side.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
