Leaking hydraulic cylinders on 1999 Mercedes-Benz SL500

How much would it be to fix the front hydraulic cylinders that work the convertible top? They are the ones that are by the sun visors.

MR cinfire there is salvation for YOU ! a company in michigan called benzseals will rebuild any MB hydralic top cyl for a VERY reasonable price . and they will replace the seals with Polyurathane seals that will probably NEVER leak again.. ive used this company and u cannot go wrong with them.. new windshiled latches from MB run 250-350 each and the main cyls behind the seats run 800 each the only drawback is they dont have replacement cyls on hand they only rebuild what u send them i think they charge 50 each for top latches and 70 each for main cyls
