I've been reading the thread. I too had a Liberty built FD trans. Paul is a great guy. I kept breaking my trans also..... snapped the input shaft 2 times, and lost 3rd gears 2 times. I have a 300m output shaft from my last trans that broke 3rd gear if anyone wants to buy it. Paul has a hard time getting them now.
I went with the T56 and I love it. The gear ratios are much better than stock. Many people have done it now so it is easier to get help. I would be happy to tell you my setup. The 350/370 path is much less common and probably more expensive.

Correct me if I am wrong Vincent but you have your 20B where the UIM is about 6 inches away from the firewall correct? This allows you to mount the bell housing and adaptor plate with no issue because you have space in the engine bay. I would love a t56, but my UIM is 1 inch away from the firewall so you can imagine the stock tranny clears the around the top of the tunnel where the bell housing is about 1/4 of an inch so there is no way I can fit a t56 unless I cut the tunnel.
Also (remember correct me If I am wrong) you have a hyper exedy triple carbon clutch which has tremendous snap bite and is not forgiving which might have contributed to the braking of your input shaft. Also do you have à chromoly input shaft like the output?
Thank you for your insights!

Stay tuned as I'm currently in the fitment stages of installing a CTS-V t56 in my 20b fd that moved back 5-1/2". It's actually in the car now as we speak but I need to massage the tranny tunnel a little bit to give it some wiggle room. I pulled my engine so I can fix some more intake leaks that have popped up recently and thought why not try an fit this tranny while I'm at it. Now that I know it will fit, I'll do the full conversion in the summer.

I know what you mean. Lol! I have oil leaks to fix also. If I was rocking the 20b lim, I wouldn't have a problem getting to that back upper bolt on the rear plate with my engine moved back. My own custom fabbed from scratch intake takes up a bit of room near the firewall. Plus having the engine out allows me to do a nice inspection of everything.
