I have a 1993 w250 club cab LE that originally had a bench seat in it, i put buckets out of a 1985 1ton dodge van (same as the stock buckets), ramcharger bases and a 1992 console in it and the seats move alot, my question is if there are aditional braces ubder the floor for bucket seats that a bench seat truck doesen't have?, and if so does any one have any pics of them they could post for me, i would crawl under a factory bucket seat truck to check for myself but haven't been able to find one to do so around here, most of the farmers have regular cab trucks around here. Any help would be great. Thanks

 

The buckets are different per say,the pass seat has a plate which bolts to floor first to allow the seat to hinge forward with the help of a gas spring.There is a small plate welded to floor that the other end of gas spring attaches to,but one could bolt or weld his own.
What is moving on your seats?

 

The seats them selfs are moving mostly the passengerside it just doesen't seam like it has enough support in the floor to keep it stable, i know i need to add some additional support to the floor but just wanted to see what the factory did for them. My bases came out of a mid 80's ramcharger so the passenger side doesn't have a gas strut but still flip forward.

 

The factory plate is just that, a small reinforcement not much larger than the flange area above it.
