I installed a 16" floor mount( https://www.summitracing.com/parts/lok-xfms6350bb)
I would recommend the floor mount type , just because it will eliminate alot of unnecessary vibration traveling through the transmission. The most time consuming thing for me was locating it just in the right place to insure i could put the shifter in first gear without hitting the bench. Overall it is a very nice shifter and made well.
