I am looking for a power top motor for a 1966 Beaumont ...thought I'd try here first. live in southwest Ontario

this is the guy to deal with if you want new

1964 1965 1966 Chevrolet Chevelle & Malibu Convertible Top Lift Motor Pump - New | eBay

I have good working used ones from a 65 Beaumont and from I believe a full size $50.00ea located in BC rams no longer available. 

Can they be rebuilt ?
