Default My 4l65e - T56 Swap - Could use some incite

Hey everyone

I have asked a few question over the year about t56 swap into auto trucks, and have collected all the info I need to get a really good understanding of how it all works. I wanted to swap 2 years ago, but ended up building my LQ9 and buying a FLT level 7 with a 3600 Triple Disc Circle D instead. Regretted it ever since I did it as I really wanted a 6 speed truck, But my TVS1900 Crew Cab chewed up its 4l60e, so I stole the Level 7 outta the RCSB and put it in the Crew Cab.....Perfect excuse to swap!

So I have collect a lot of the parts I Needed From GM

Pedal Assembly - 15027983
Pedal Assembly Bracket - 15713209

Top and bottom Column Covers to hide shifter - 26072994
Pedal cover - 15706041
Master Cylinder and Line - 15727261
Cross Member - 15748078
Switch - 15027967

I have also already gone through the paces and ordered a Tick Stage 3 viperized GTO T56. Trying to decide which clutch Im gonna run on it, Truck doesn't see alot of driving, only a few thousand a year, but i do beat the ever loving **** out of it.

Few questions I have tho. Looking at the pedal assembly, and clutch master, what is suppose to connect the pedal to the master? I see the master connects the to pedal assembly etc, but were the actual rod to the pedal goes theres nothing....what gives?

That master looks wrong, it should have a ball at the end that snaps into the pedal. Here is the one I'm using: Dorman CM350124 Clutch Master Cylinder : Amazon.com : Automotive There is a white ball piece that isn't shown, it's like a bushing between the master rod's black ball and the pedal.

And once you get it, do yourself a favor and make it adjustable. I lathed down some of the black plastic on the rod, cut the rod, tapped both ends at the cut, and installed a coupling nut so I could lengthen or shorten the rod it still installed.

I got this MAster in today, Looks much better as far as engagment at the pedal, however it doesn't have a very big line on it.....Goes GM make a line I can use? I know I can rob the line from the other master, but Id rather return that whole assembly

One I got from gm is the same as the car quest one I got.

My understanding is that everyone bought masters and lines all in 1....or is everyone making a line
