you are vested and should receive a pension. in the Western Conference if you are disabled you can receive 85% of a full pension. also here it is 80 and out. you could wait 6 more years here in the west and collect 100% of a pension.
you could apply now and receive only 55% of your full pension.
where you are at could be completely different. find the phone number of your pension office and give them a call. find an old statement. it has a lot of info. don't write. it takes about 3 months for a reply.
you are better off calling your pension office for the right info.
