need 69 or 70 250e track
i am new to vintage sleds. i have always loved the mercury 250's and finally had a weak moment and bought one. i will tell my wife later. anyway, the front drive gear is not engaging fully with the track. it makes a very nasty clunking noise when the sled tries to move forward. i have the new drive shaft/gear but i dont want to put it on until i get a decent track. i dont have any adjustment left(to tighten track) and many of the stainless steel clips(in the holes on the track) have fallen out. is this a good indication that the track needs replacing? are there any aftermarket universal tracks out there? what years fit this sled? any help is very appreciated.
