So earlier this year I bought some stock power 60/40 Gbody seats for my Regal project that are brand new and have never been installed in a car and they came with new GM carpet and the rear seat covers.
After doing initial test fitting I found that the driver's power seat just did not go far enough back for me to be comfortable, I am thinking since these are the "Brougham Comfy Chair Seats" that with all the extra pillow padding that has never been sat on that it is probably making me sit higher and farther forward than some 30 years old worn out seats.
So anyways I made some brackets to set the seat back about 2.25" using 1/4" steel plate and then I welded in stainless 3/8" bolts to mount to the seat brackets and used the original hardware to mount the brackets to the floor.
You can hardly tell from looking at it with the seat installed but a huge difference in how I sit now.
