I did a search and found alot of conflicting information as far as using a T56 with 3rd generation pedals. Who is using the sock pedals with the 4th gen tranny? Does it work ok without modifications? The reason I want to try to use them instead of the 4th gen pedals is because I heard that the holes won't line up with the 3rd gen holes. If anyone has any input, I could sure use the help.

 

Both pedal sets are essentially the same. You can use either. The four holes that line up with the brake cylinder are the exact same, but teh fifth bolt up top may be a little off due to a slight production difference. Either works exactly the same in dealing with the clutch slave and master cylinders. This is assuming you're talking about pedals from a hydraulic 3rd gen which is I believe anything after 83.

 

Thats good news. I have a 700r4 and wanted to go to a T56, and thought it would be best to try and use the third gen pedals off a T5 car so I could use the indentations in the firewall to drill. If you say they are the same though, I guess it doesn't change anything. One more thing, does the clutch master cylinder mount with the same bolt holes?

 

Ok that is what I did on my car, I installed some third gen pedals on it and found out that the fourth gen master cylinder rod end would not engage in the clutch pedal stud, the stud was to big (and smaller if I can remember) compare to the fourth gen one.
And even if it would have worked the clutch pedal would have been A LOT higher that the brake pedal, seems that the master cylinder rod is longer that the third gen one.
Then I found myself some fourth gen pedal assembly but didn't want to use that ( not has strong and doesn't have the 2 holding rods ) found on the third gen ones.
I decided to use only the clutch pedal from the 4 gen on the 3 gen bracket but you have to have a bushing machined for the pivot point because the diameter is not the same as the 3 gen, but still didn't work because the master cylinder rod came in comflict with the bracket.
MY FINAL solution was to weld the 4 gen stud in place of the 3 gen one and relocate the bracket that is welded on the pedal so the pedal was now at the same level with the brake pedal.

And now using a MCLEOD master cylinder with adjustable rod end that allows me to move the pedal up and down to my taste :lala:

 

Hmmm....I'm using the stock 3rd gen pedals (because they went for much cheaper on ebay at the time i was buying them) and bought a new master/slave cyl assembly and the pedal doesn't "stick out". I'll see if I can get a picture. As for the fitment I took the 3rd gen master cylinder rod bushing and bastardized it until it fit into the 4th gen cylinder hole and used a c-clip to make sure it wouldn't slide out. It doesn't look pretty but it works just as good (there is no slop).
