O.K., Got this starting probelm with my 1950's Clark model c40mb-193-782 wondering if someone can help. Details are such.

Try to start and clicking noise from starter, keep trying and after several tries it might catch. I assume solenoid or starter motor problem. Took starter out. What is the appropriate move from here? Rebuild this starter including new solenoid? or buy aftermarket starter? Is there a starter rebuild kit with bushings, bearings, solenoid and where would I find parts? What do you think and thanks for the advice.
