It can be done. I did it with mine except I put SS trimmed seats in mine and kept the bench. Looks factory still which is good.
Have you got the stato seats?
Is the passenger side electric or anything flash on it?
You have to put your trimmers hat on to do this.
I had to remove the seat back from the base on both the donor seat and the bench. Thats easy; a couple bolts each side and they are interchangeable.
Then you have to unclip the seat fabric from each seat base, these are held in with metal staples, just spread them and reuse.
The bench side you will have to carefully cut the fabric between the seat and the bench as it is sewed together.
When you put the stato seat bottom on the bench frame, you will have to cut a little of the seat bottom fabric to get it over the tube supporting the bench.
I sewed this back together with a needle and thread.
Looks the goods once done, just need to take your time and have patience!!!!
