Getting a third seatbelt in the back

[craigger007]

Am I correct in a assuming the original back bench did not have 3 seat belts? We just had our third kid this year and I've figured out how to fit 3 car-seats and boosters in the back for my kids, but there isn' a middle belt.
Do you guys see any problems with sharing a middle buckle on the current belt blots that come out of the floor?

Thanx,
Craig
