Why screw around with bodgy adaptor plates when there is a factory bellhousing available? Do the job properly man, buy a 1JZ box.
If I can find a 1JZ R154 in my price range I will. As everyone knows though, they are as rare as rocking horse shit. Yes there is one for sale down in NSW, he wants $1700 for the box and clutch and flywheel. It may be a good deal, but at the moment with the money I have its just out of my price range. If I could get the box just by itself I would buy it, but at the moment he isnt seperating.
Like I said, I found a R154 with a 7M for $1200. If its goona be too exxy/hassle to put it on a 1JZ, then I wont bother.
