you need the flywheel and clutch for the transmission you have, not the engine it's mated to. so you do have an ls cable trans then? if so you need to be certain whether its 90-91 or a 92-93. the later model years had a 1/16" larger input shaft on the trans, so you have to make sure you order the right year clutch kit. flywheels so far as i can tell from all b-series are interchangeable
