I've re-foamed 6 Advent woofers. The first kit came with shims for the voice coil requiring removal / replacement of the dust caps. I did it as instructed and they work fine. Later kits did not include dust caps so I didn't shim the voice coils. Those drivers also work fine but took less time. Old Advent drivers have a masonite reducer ring that I removed on the first set ( kit with shims ). I used silicone bathtub caulk to re-bond the masonite to the baskets with an army of clothespins to hold it together while it cured. I don't recall exactly what glue I used on the cones but it was not rigid white glue nor was it contact cement but it is flexible. Later (but sill old) Advent drivers eliminated the reducer ring by altering the basket stamping and are easier than the masonite units. Figure an hour on each driver plus any drying / cure time of the glues. It's well worth the effort.
This is way more than I paid but will give you an idea.
