If the GT is cheap enough, no more than $300 then worth trying.
If you have no mechanical and artistic skill and/or have nobody to help then don’t bother cos little adjustments are always needed.
I’m both the aforementioned things but can’t be bothered doing it haha.
If I recall the 159 seats bolt straight in if you look at the threads here you will know.
I don’t doubt your willingness to have a go and it takes more than that to make it happen.
Also , workshop places don’t want this work so don’t expect that help.
I’m trying to be helpful here.
