for the automatic, I disconnect the front bushing at the transmission, remove the carpet, undo the 4 bolts holding the chrome shift assy in and pull the whole thing out.
on the bench, install the rear bushing from the shifter to the liinkage, install the front bushing, re install the whole assembly then connect the front bushing at the transmission.
this is much easier than trying to access the rear bushing from underneath.
