Sorry, missed the part about getting the hoses off.
You would benefit from new rubber hoses. In the rear, especially the passenger’s side, you will want to cut the hose as close to the top mount as possible. Get a 14mm (I think... it might be larger) deep well socket and put it over the remaining stub. Listen to Perry... use an 11mm flare wrench (got to PEP Boys and buy one if you don't have one) for the hard lines. While you're out shopping, get a MAPP torch. Heat the union before attempting the removal. DO NOT overheat the hard lines as the MAPP torch will literally melt them. If they get cherry red, allow time for them to cool before wrenching otherwise you will twist them like licorice. You may have to reach through an access hole in the tin to properly apply the flare wrench.
Good luck. Getting the soft lines off the rear is one of the worst jobs (2nd behind getting those rubber grommets with the tubes in them back in the top of the M/C).
