Something to think about is if you are going to get the T56 Magnum customized.
I went with RPM transmissions because I could get a few tweaks and mods that were not available at the time from others (or at least I could not find anyone else) such as machined bronze fork pads, machined bronze shifter bushing, upgraded carbon blocking rings 1st-4th gears as well as micro-polishing, etc.
Not sure if these are items you are interested in, but it may be and it's nice to get the trans-in-a-box to be ready to bolt in.
