Identifying '69-71 Mopar B and E-Body 6-Way Seat Adjusters

From 1969 through 1971, Chrysler offered an optional manual 6-way seat adjuster for the driver's side on B-body and E-body cars with bucket seats. This unit lets you adjust your seat for height and tilt as well as the normal fore and aft. It works very well and is easy to use. Chrysler cancelled the option as of 12/1/70. The option code for the track is C62. If you have a car built after 12/1/70 and it came with a 6-way, I'd be interested to hear about it.

Click here for information on the under floor reinforcement plates required for E-bodies and 1971 B-bodies.

If you are missing the chrome knobs used to adjust the seat position or just want new ones, they are available from Tony's Parts. www.tonysparts.com.

Note that the tracks below may not have all of their springs on them. As I find better pictures of complete units, I will update the site.

1969 B-Body

Will also fit 1968 B-Body cars. Easiest way to recognize this unit is that the front seat mounts have studs sticking up. Also the inner seat mounts point inward where all other years point outward.

1970-71 E-Body

This unit is easy to spot by the for-aft control lever which curves around front of left track. Requires underfloor reinforcement plates. Plates are same ones as used in '71 B-bodies except they don't need inboard spacers.

1971 B-Body

Looks similar to E-body but does not have curved fore-aft control lever. Requires underfloor reinforcement plates. Plates are same as ones used in '70-71 E-bodies. Note that steel spacers are required between the plate and floor at the inboard seat track bolts as seen in the image below.

Underfloor Reinforcement Plates

Reinforcement plates are required on 1970-71 E-bodies and 1971 B-bodies. They are mounted underneath the floor pan, small metal straps with studs mount from inside the car to retain the reinforcement plates to the floor pan. There may be metal spacers between the reinforcement plates and floor at the inboard seat bolts. These spacers are required on the '71 B-bodies but it appears that not all E-bodies used them as they have an extra reinforcement already in place. Note, some are welded to the plate and some are loose. If you don't use the reinforcements, the floor can be damaged. These plates are often missing, rusted, or forgotten. Reproductions (as shown in the photo at right) are available from Resto Rick, www.restorick.com, or other sources.

Click here to visit the Hamtramck Historical site to see how to install a 6-way seat adjuster and reinforcements in an E-body. This would be similar for a '71 B-body except that the B-body requires spacers between the inboard end of the brace and the floor. Other models just replace the existing tracks.
