83/84 atc 250r frame DIFFERENCE?

[1972mercury]

I have a 83 250r frame kinda bad shape but have a better 84 frame and was thinking about transfering everything from the 83 to the 84 frame but is there a difference ?

dont think so . the only difference I know of is the swingarm ,dogbone assembley buy if you take it all of I think it should all bolt up into the 84
