Any info about 919 Park Place history?

You all seem to know a lot, so can anyone tell me what they know about the history of 919 Park Place (at NY Ave, across from Hebron school)?

We have been living here for a year and have always suspected that they are illegally de-regulating the rent-stabilized units. We have a ton of evidence, but we need to know a few more things to confirm.

Has the building ever gone co-op? If so, when? What percent went co-op and what happened to the rest? Where people ever kicked out if/when the building went co-op?

Any information on these issues is much appreciated.
