T-56 Magnum 6 speed manual transmission EARLY A-BODIES!!!

How does this T-56 Magnum differ from the stock T-56 that is in my 1996 Z28? Because I hurt my T-56 pretty bad at the drag strip just by missing 3rd and getting 5th instead. The whole trans had to come apart.

Jamie's 5 speed looks pretty darn strong from the pictures I saw in Mopar Action a couple years back.
