Over 35 years ago I dismantled an FE or FC Holden and still have the gearbox in Adelaide.  It was working fine before the car was dismantled and it has been kept under cover from the weather all those years. 

Would this gearbox fit either model?
Do you think this gearbox might still be useful to someone looking for an original?
What do you think would be a fair price for this old gearbox?

Thanks for your advice.
