Hi all  
i badly need yr help as I'm new to ford and I've bought myself a Canadian built RHD UK new 1964 Galaxie 500 convertible with a 390 an auto box 
shes fairly solid with a little bit of rust along the rear inside trunk seam. Trunk lid and left hand door (yr drivers my passenger) are rotton but she came with gud replacements shells.

my first problem (of many I'm sure) and question is on removing the internal window mechanism I've found it to be partly unusable and have possibly sourced another complete door state side but noticed that its coming from a 500xl 2 door coupe/fastback
i think it'll fit ok but it's fitted with power windows where my only had manual hand wind.
will I be able to use this door and are the internal parts interchangeable ir can I easily remove power regulator and refit manual?

sorry it's long winded and much appreciation for any and all help
