i was reading the post a 57 sunliner for sale,    mentioned in the post was,  the top can be moved up or down by hand,   i didn't know that,  or is this the only one?,    i havn't had any problems with my top operating,  but,  when the time comes that i do,  knock on wood,  can they be operated by hand?,  if so tell me how.  thanks   Jerry

you have to pull the top ram pins one on each side and move the rams out of the way its better just to fix it to work rams and pump can be replaced
