Speaking for the SC pedal box, I can say that the bronze bushings seem to operate just great.
The job itself is not hard, just tedious. You will need access to the bottom of the car to undo 2 hex heads and 2 bolts, remove pan, now you can access front pedal box nuts. The other two are accessed from inside the compartment.
There is a large spring that holds the clutch pedal. This spring gets in the way of removing the large hex bolt in a horizontal plane, accessed from the left side, next to clutch (this bolt holds on the support bar that goes up to the master cylinder area). Use an 8mm bit from a socket, or have an 8mm with a short end that is very short; this provides access to the bolt.
When I put everything together again, I put the spring for the clutch on BEFORE I put the pedal box back into the car. Then, I had to hold the clutch pedal in a very specific positon for access to and tightening of the hex bolt. Alternative is to put the spring on later: if you do this, make sure you cut long spring end hook down a bit to make it easier to hook the spring back on.
Assemble everything at first loosely. There is a sequence of reassembley that goes support bar, brake pedal rose joint and clip, then trunnion pin from clutch cable to ear of clutch pedal shaft.
This is all evident once you get it out. Easier than it sounds, and worth the trouble. Also, after seeing the plastic bushes I am certain that the bronze ones, while possibly not tight at first, will exceed the nylon ones over time in terms of fit and wear.
