I agree with 46gmcpu - removed my seat tub some 15 years ago and installed various buckets since, the latest being late model Dodge pickup seats with integral shoulder belts. With V8 power and a heavy foot I think the structure might have had some issues by now and it of course has not. The tub is NOT a structural part of the cab - spot welded seat riser.
"Until I see your degree" really? New to this site but I may just have the shortest membership ever if this is the attitude and feedback seen on the forums here.
