The earlier (steel type 3AJ) swingarms that had 18" rear wheels are actually the same length as the 3TB/3AJ arms.
There are basically 4 types of XT600 swingarm.
1) Alloy 34L/43F narrow & drum type - (shorter than later steel arms)
This type includes the original 34L arm that had the snail adjusters on the inside of the arm.
2) Steel 2KF narrow & disc type.
3) Steel 1VJ wide & drum type.
4) Steel 3AJ/3TB/4PT wide & disc type.
'Narrow or Wide' referrs to the width of the front, pivot part of the arm.
Kick only bikes had a narrow output shaft, chainline & frame where the swingarm pivot bolt passes through. It isn't easy to interchange narrow & wide arms.
So...you already have the longest arm available!!
The only 18" tyre you might have problems with are 140/80/18 Michelin Deserts as they're much bigger than any other 140 section tyre.
