picked up a 8 tooth drive axle off ebay for 29 bucks got it and it wasnt the one pictures it was a 9t so returning it and went down to the local dealer and just bought new ones. out the door he said 80 bucks so should have went that route from the start. I have the 23 and 38 gears. so need to decide if i want to replace my chain and drive bearings since it will be apart. there is 8900 miles on the originals. thinking that over the summer i should do the top end of the engine , either rings or piston kits
