TR250 Seats - What's Wrong?

I knew the seats were stuck when I bought CD954L. I drove it home 150
miles, barely able to reach the clutch pedal all the way to the floor.
My wife is a few inches shorter than I am. It's her car too, so this
weekend I had to go after it, or else ;-(

Not much problem getting the driver's seat out of the car - judicious
use of BFH moved it a bit so I could get to the bolt heads. It was
obviously not the first time a hammer had been used to move the seat...

The problem turned out to be the pair of rollers in each track. They had
rolled together. The rubber "tires" were pushed against each other,
making an effective friction lock. Finally was able to get both tracks
off, through injudicious use of the same BFH. Cleaned them up some, and
lubricated thoroughly, and tried to put them back together. 

The first thing I had to do was drill out dimple 5 in the lower channel
(the one that bolts to the floor - see clumsy attempt at ASCII art
below). Then I started sliding the lower channel into the upper channel
from the rear.

       5                                                  6

I put the rear roller in (the 'O' - it's bigger than shown, actually too
big to get past the dimples) when the front of the lower channel passed
dimple 1. When it rolled up to dimple 2, it bound. I used a locating rod
(OK, a stick) to push it back to dimple 1. Had to repeat this a couple
times before the front end of the lower channel passed dimple 3, at
which point I put the front roller in. After that I no longer had access
to the rear roller with my stick. Manually operated the slide back and
forth a few times. Apparently, the rear roller worked its way forward,
and the front one worked its way back, so they were all the way up
against dimples 2 and 3 at the same time. Oh, &!^%. It was locked up
again.

How is this supposed to work??? Is there supposed to be a spacer to keep
the rollers the right distance apart? Are my seat slides toast? Is there
a recommended replacement slide that can be adapted? Does anybody
understand what I'm talking about?
