You are correct, unfortunately I did this back in 2003-2004 back and don’t have a clue where the photos are. Me taking underdash pics probably won’t help unless I take some of my panels down, which I don’t really feel like doing right now. Next time I’m under there with the panels down, I’ll snap some photos
I used a 84 S10 manual clutch pedal and 3rd gen master. The S 10 bracket (left) had the clutch pedal assy riveted on the side, i drilled the rivets and drilled 3 holes and bolted it on the g body bracket.
Master push rod on a 3rd gen is real long, ground the crimped on end off and welded a nut coupler on, the centric master i used had a 1/4-20 thread on the end so i turned a $40 master into an adjustable one. Nook and transmission sells a custom O ring to -4 end
The geometry was a bit odd and the firewall was too weak and i bent where it bolted to and bent the push rod on my first master, i built a shim to get the geometry better and strengthen the firewall to told the master. No pics installed but you can use your imagination.
