Fork Replacement

[Estecks]

This is my first post, I have been gathering a lot of information from you guys for a while now though, but decided to register. I have a 1992 XJ600 and I have bent front forks that I will be replacing. The forks come in Wednesday and I was wondering if there is any tutorial or walk through on how to replace them on this bike? BTW, the new forks I got comes with the tree (idk if thats what it is called, thats what my neighbor called it) so it's not just the two forks, it's the whole set. I'm told to replace the fork seals on these forks, is that hard to do. . Thanks in advance and I am glad to be apart of this forum!!!
