I would go for adjustable springplates from Creative Engineering. With this option it makes things alot easier and you will have easy adjustment and tyre removal.
The job is relatively easy, depending how all aof the bolts come off. It took me about 2 hours (not including blleding the breaks). It is pretty straight forward and I think you would see how to do it as you went. The brake line is the only pain, it is a shame the spring plates don't have the same notches as the creative ones. It would be a really easy job then.
