71 Duster- Rear Bench Seat

Since I got my car, in 2011, the most difficult part I have to install is the rear bench seat. In the past I have turned hydraulic floor jacks, on their side, and used that to press the seat far enough back to engage the hook to keep it in place.
My age and disabilities are catching up with me, to be able to muscle it into place

Does anyone have any tricks to push the seat back to engage the retaining clip?
Maybe if I put a rope around it and ran it out the trunk, tied it to a tree and then pull the car forward. Yes I know that is ridiculous
