A big bonus of using the patented cast aluminum J.W. bellhousing (PN: 92454-A) over a cut-to-fit adapter is that it's 600 times stronger than stock, and doubles as an SFI-approved flexplate shield. Throw in the fact that it costs just a smidgen more than a flexplate shield at $300, and the decision is a no-brainer. With over 40 different Ultrabells in its catalog, J.W. probably makes something for whatever motor/trans hybrid combo you can dream up.
