Does anybody know if the YZ450F's are a direct bolt in swap for a YZ426F?

What about the WR's are they all the same fitment/cases?

Do the 450's still use oil tanks, if not what year did they do away with them?

Thanks

Im almost 100% sure the bottom motor mount is very very slightly different, slight enough you could likely dremal the hole out enough to fit without making new mounts, if i remember right its a few hundreths of a inch difference, just enough the bolt wont go through, please dont quote me on this, i have read this elsewhere on this forum, so i asume the person who posted it tried it to know the exact differences.

06' was the first year to not have an oil tank.
