will a T56 bolt up to a 90* V-6? my understanding is that the outside mechanicals of the 90* V-6 are the same, such as the same bolt patterns for the transmission. is this true?

physicall it will bolt up to the engine. actually, you would probably have a problem getting the right clutch setup for it, i.e. flywheel, clutch disc, pressure plate, release bearing, etc...
