Your gonna get the same replies I did... Not enough people have done the swap to really know, so were just gonna have to wing it.
I don't think the T3650 mounts in the same place as the T45. To answer the question you asked on MCE, the pedal assembly I got with my swap was custom built. I'm not sure who built it, but I purchased the Swap kit off of "lugnut" he's basically and inactive user because he sold his vic, but he will probably answer PMs sent to him.
If you want we can meet up and you can check out the pedal assembly and take some pics if you want.
