hi I have the fiat doblo 2001with the folding bench seat and want to know is it possiable to change to 60/40 rear seats.if so whats needed and how.

I think is not possible I was thinking also for this. I was a owner of a 1.3MJ 2008 with 40/60 back seats. Now I have a 1,2SX 2002 with 100% back seat.(downgrade ) Have I seen on the old one, the lever for pop-up the 60% seat is located in the middle of distance of this 60% seat. In that case you can pop-up/fold only the 100% seats or only the 40% seat. You can not pop-up only the 40% seat, only fold them. Maybe the reason is the seat belt for the single seat, you can not use it because the lock system is on the 60% seat.

In our case, the lever for pop-up the three 100% back seat is located in the middle of the back seat, in the same equal distance from left-side. Only way is to modify the holders from the floor of the car.

sorry for my english, I hope I was usefull
