I recently bought some gears from a friend of mine(410's) and all I got was the ring and pinion from him. I made an appointment with a shop on Thursday but I didnt order an installation kit.

So now I either take the car in to do the basic swap and no new crap, or I wait maybe a week, and get an installation kit to go along with it. My car has 50,000 miles. Should I go ahead and cancel because I dont have the kit? Or should everything be ok back there? My car has been regularly maintained in every aspect. Anyone do just a ring and pinion swap? Or will I be pushing it and playing with fire? Thanks
