Steve its a fairly easy car to biuld there is some sink marks on the trunk and on the top of the front fenders that need filling . Ive made a new hood hinge as the kit one isnt very good and ive moved the gun sight orniment from the nose to the hood as its ment to be.Its simple to lower as well becuse the axels are those metal rods. yes it would be possible to make the station wagon to a custom hard top . The only thing is the glass is in one peice so opening the tailgate would be tricky. My body shell was a bit warped so that had to be put right and once its put together its not noticeable . I hope this helps you
