Post up some pictures when you get a chance.
As for the top, It depends if your potential cruiser is a hard or soft top model and if you want to keep it more original to its build.
Aftermarket Soft tops are manufactured by a couple companies and can be supplied with the needed aftermarket bows. The soft top doors are harder to find but can be found via the classifieds section or ebay if you're patient and depending on how much you want to spend. You can also use hard top doors with some slight modification to the soft top bows. Overall look to spend anywhere from 1500-3000 for an aftermarket soft top and bows. and around 400-1000 on a set of doors.
For the hard top, The early cruisers used a "corregated hard top" *Picture for reference:

Those are harder to find but can also be sourced via the classifieds section with some patience. The price of those range depending on how much you need it and how much the seller wants to get rid of the top.
Later model tops can fit with some massaging but they are not true to the build. It's really up to how original or not you want to be.
