:D

One of the rarest chips out there, I believe.

You could buy a green MXR delay off of eBay for $200 and rip it from there...

Or you could endlessly search the wholesale IC lot sorta sites like doom.com until you found someone with some, then buy 200 of them for $5 of them each.

first,you'll need the datasheet...find how many stages the bbd is,and then substitute it for a similar number of stages bbd...probably you'll have to build a daughterboard ,because the pinout won´t be the same...i guess the 3208 or 3207 from steve will be the most suitable ....
