This should be a trivia question on "Who wants to be a... Triumph Wiz."
For all those wondering, here's an explanation. Glad to see a newbie like
myself can still teach a few old dogs new tricks :-)
Each seat requires a Seat Slide assembly (Part 821137/8; TRF Part catalog
pg 447; Bentley pg 451), also referred to as a Seat Runner, to secure the
seat to the floor and provide forward and rearward adjustment.
Each of these are comprised of two sliding tracks, one left and one right.
Several Triumph models use this part (TR6, 250, some TR4, possibly GT6 and
Spitfire).
Each track consists of two pieces, an upper and lower track. When these
tracks are taken apart, by sliding them entirely in opposite directions, 4
rollers can be found (two per side; one front, one rear). Each of these
rollers assist in the "slide" action of the seat track back and forth.

The rollers are held in place by a simple "notch" which serves as a
stopper to prevent the rollers from hitting each other or falling out. A
few taps with a light hammer will result in the rollers to "hop" over
these notches and release the upper and lower tracks from one another.
The rollers themselves, each use two O-rings (see Diagram 2), eight
required per seat slide assembly. The o-rings provide a smooth and quiet
slide, by preventing metal touching metal.

Over the course of time, these o-rings become worn due to friction, or
develop flat spots by maintaining the same position(s).
While this type of restoration goes far beyond typical, and is most often
unnoticeable, it is easy and inexpensive to perform, and will provide
years of trouble-free high-speed seat adjustments. IMHO, if replacing the
carpets or refurnishing the seat cushions, why not address this as well.
