I got your pm. I planned on running the auto from the begining of the build. I looked at the site and was confused that they did't seem to have anything for an R series. I not sure that a w56 would be up to the task of a 1uz in a heavy rig. One question I had was if the input length on the W's is all the same and if this would matter. The reason I ask is the R's have several lengths.
I am a fan of the 7m. I was originally going to use it in my build until the lexus fell in my lap. It did pretty good in my 4runner with 37"s and 5.29s. I think with 35"s and 5.29s in a single cab truck it would be quite fast.
My buddy has a toyota trecker that we have been talking about putting the 7m in but we are lazy so it's been sitting under a tarp in my backyard for 6 months.
