I dont think the FDNY has any rearmounts in front line service older then 2001. Do they? They have some spares but i thought that was it. Also Ferrara on their website has one that is 102'. ( LP 102' RM Ladder pg. 3 of this thread) That is probably what the FDNY rigs might look like.
Sorry buddy, your wrong;
Following FDNY ladder companies run 1999 Rearmounts;
