What parts are needed other than the swingarm and a new shock to upgrade from the a style stock swingarm to an h style? I just bought an aftermarket shock but it is slightly too big to fit in place of the stock on, so I am debating whether or not I should upgrade my swingarm or get a different shock. I don't want to spend alot, so I'll probably go with the a different shock, but I'm just curious what is involved in the swap.
