1984-1988 Corvette Manual Transmission 4+3 Doug Nash Main Case, this is a very nice original case that was professionally cleaned and inspected, there is no damage or issues, this could be a direct replacement for an original or utilized for a Super T10 build since the case has the same internal dimensions, this is a very well designed and strong case for performance applications, thanks for looking and please check out the other items in our ebay store.
