I need to replace the bushing at the ball where the gear shift lever is seated on the center console. There is a plate holding it in place, with two bolts sticking up and nuts fastening it on the top. Can I remove these nuts and will those bolts stay in place, or wiill they fall into the gearbox. Do I need to grip them from below while removing the nuts? Can i replace this bushing from above? This was done rather simply by a mechanic once, and now I am attempting it on my own. I have ordered a few bushings from Pelican unsure of which was correct, happy to do that. Appreciate advice.
