Power Seats to manual

[84 Bonny]

The power seats in my 84 bonniville are bad (transmission), is there a way I can keep my same seats but convert them to manual? as the seats are in great condition. Is there a way to manually move seats so I can be in a ,more comfortable position? they are 60/40

Go to the junkyard and pull the non power track set off another G body and you are there. It's a bolt on interchange.
