I know its not bucket seats but I'm still working on fitting this in mine (newer middle row suburban seat). I had to narrow it by two inches. It will fit now just got to figure out seat belts. I plan to go 5 point harness shortly.
There is a guy in the build threads he did durango bucket seats in his he had to cut and widen the wheel wells for it all to fit. He made three threads on it part 1,2 and 3. Ha ha.
Grandboost also installed a single YJ bucket seat in the back of his, I think they are to wide to go with two back there.
