1992 Ford Mustang t5 Mustang tranny

Hello my name is Joe I recently bought a 92 Mustang GT that had been in a wreck approximately 10 years ago I bought this car to do a 5 speed swap on My 89 LX 5.0. I was just wondering where this car sat outside for the last 10 years under a tarp if you think the internals of this transmission would be damaged due to sitting and/or condensation build up over the years, the drive shaft was taking out of the car as well last year - thank you Joe
