Power Seats for 89 Suburban

I have an '89 Suburban Silverado and want to upgrade the seats. The seats are not very comfortable for long drives and would like to replace with power seats or maybe a manual adjustable seat that has the same support adjustment as power seats. Does anyone know where such seats can be purchased or if there are seats from other vehicles that could be mounted in this vehicle with custom brackets. I would also like to replace the second seats with bucket style seats as well. Thanks

I had a 1989 silverado suburban 3/4 ton that I sold about 3 years ago. it had electric bucket leather seats in the front and captain style leather seats in the middle. If I remember correctly the suburban had a tag on the back tailgate that led me to believe that it had been upgraded by a third party for the dealer. may want to keep an eye at the truck recyclers, maybe you will get lucky. or try a custom van shop, I know they have stuff for suburbans too.
