hi guys,been a member for a while,never posted but here goes,how do i tell what serial # it is without the actual serial plate which is gone,i got it (1989 743)from a local farmer that has had it for 20 years and i wasnt worried about it being stolen because i trust this man,any way is there a way to determine what it is so i can order parts,the dealer tells me i need the serial because they changed some stuff,when i looked at the parts manual for electrical there seems to be alot of differences in the different serial #s,any help would be helpful,i was told it was a 1989 and when i sandblasted it it says 1989 on the rims and due to paint layers i think they are original
