The GM A-Body is the quintessential General Motors Musclecar from the Musclecar Era. Larger than the pony cars like the F-Body Camaro and Firebird or X-Body Novas. The A-body and chassis family included such legends as the Chevrolet Chevelle, Malibu and Monte Carlo, Buick Skylark and Gran-Sport/GSX, Pontiac Tempest/LeMans and GTO, as well as the Oldsmobile Cutlass and 442. The A-Body has two generations, 1964-1972 with some differences from 1968-1972, and then the bigger 1973-1977, before General Motors transitioned to the G-Body in 1978-87. American Powertrain has all the parts and expertise you need to upgrade to a 5 or 6 Speed TREMEC transmission, with expert engineered vehicle specific parts to make the job easy. We also offer complete differentials and crate engines.
