I had the governor gear problem on my 91 300D also. Part from the dealer was < $3.00. It can be done by lowering the trans by removing the rear crossmember and moving the trans as far as you can to the right side of the car. I tied mine over with a strap to hold it there. I found 1/2 of the gear still on the governor and never found the other 1/2 of it. That was about 10 years ago. Still running great.
