I replaced the gear and bushing last week.They were in there for 7 years,,over 50k miles and were plain wore out! Todd has them in stock. No spacers or bearings and the bushing has the oil grooves.
Al can the new bushing be installed with engine in car and cam still installed?
Absolutely.
There should be a thread from the last 4 to 6 months that talked about what tools can be used to remove & install the tower bushing.
