Yes, the pressure plate on a Street twin is completely different design than the LT1 pressure plate.

Not sure about the LT1 but you don't have to with the LS1. There is an adapter plate that bolts to the flywheel (standard pattern).

If it is for a LT-1 yes you do because the floater plate pattern is drilled in the flywheel. Also the flywheel is thinner than a regular single disc flywheel to keep the overall stack height within the factory 4.950" bellhousing.

Thanks, extensive searching into the matter (LS1tech, camaroz28.com, and google) yielded nothing.
