I don't know if what I have would fit, but whatever you decide to go for, measure the distance between the seat runners... :-)
It's unlikely my "surplus" seats would fit your aeroplane, and the cost of shipping from the UK would be prohibitive.
I'm hoping to pass them to another FRA150L that does have the right runner separation: G-BCFR, the aeroplane in which I had a share.
We learn from our mistakes :-)
Good luck
