Mostly luck I think, it was posted in the hot air section of a Buick board, so not many people saw it.
It was local, too.
... and before you ask, hot air = 84-85 non intercooled cars. The block/heads/crank/rods are identical. The only real difference is the oil return from the turbo on a hot air is in a diferent place, so you either have to drill the block or the pan for an oil return.
Otherwise, everything from an 86-87 bolts up.
