Rear sprockets to suit 1979 yz250

[loosecannon]

G'day guys,

Just trying to find out what other year model rear sprockets will fit on my 1979 Yz 250? , maybe something from the late 80's or 90's might be the same

Thanks in advance

Dave

Yamaha ran the same bolt pattern rear sprocket till 98 on YZ's, With different teeth numbers of course depending on bike size & year model,also most IT's ran the same sprocket
My parts book says 48t for the 1979 model 250

I thought there would have to be other that would bolt up
