1997 Yukon Seats

Currently have a broken riser/slider (manual)for the pass seat. Looking to replace but slider/riser cost almost as much as a seat..... but all the seat I found are either electric or 200 and up..... The question is how hard is to make the connections to make my pass electric and or how hard is to install 2000 and up seat on a 1997 yukon...... thanks to all.

Any ideas???????
