After doing much searching I cant find a clear answer to my question…

This almost answered it:

I acquired a pair of 1000 seats and bought some 1×1 stock to weld to the frame – and have an opportunity to get 1000 pans w/built in sliders. I was wondering about the height differences…and this thread almost answers my question. Are the 1000 seats w/1000 pans the same height as 900 seats/pans? I also have a 900 slider in the drivers spot, which is kinda tall. Will the 1000 seat/slider pan be shorter than the 900 version? Good to know before I begin welding, etc..
