Steve I have an 1979 928 Porsche that I've been restoring for awhile and the manual transaxle would grind bad going into first gear when coming to a stop indicating bad synchros so I called called 928srus.com where I buy my parts and he said don't rebuilt the box yet try changing out the oil from 90 weight gear oil to red line synthetic gear oil. I don't have a lot of faith in snake oil treatments but I did and it worked the synchro is still bad but you could shift it into first without stopping. Sort of putting a Band-Aid on a amputated finger but it still worked.

The cheapest way to buy oil is from a oil company in 5 gallon buckets, I would bet you have plenty in your area, I buy from a place 100 miles away but they deliver to a hub in Springdale AR for free which is 25 miles away. Keep us in tune on what you use.
