MAC 38-The T-5 bolts up to any modern GM bellhousing/trans pattern. That is all trucks after 49 or so and all Chev cars after 55. This S-10 unit would be fine, however these units were behind 4 cyls and small V6s and not really stout enough for severe punishment. A local buddy has been running his T-5(4cyl type) for a couple years now without trouble, behind a 235. The ultimate GM T-5 was from The Camaro/Firebirds, V8 powered. For the older truck application the trick is to use the Camaro T-5 but swap on the S-10 tail housing which moves the shifter way foreward nearer to stock location. You guys need to read all the tech tips here and at Inliners.org. Like my 46, the older narrow cab trucks make a good home for the T-5s as no side linkage is required. I ran a saginaw 4 speed for many years, was fine but I like the top loader better plus you get OD gear.
