heater core alternative

Does anyone know of an alternative to part # RTC7433. This is a heater core from a LHD 1986 110. Mine started bleeding coolant. OEM replacements are upwards of $600.

RTC7433 is the heater core from 83-93 lhd trucks with the same in dash system as the NAS 110. Many of the parts for these systems are NLA. Fairly rare part for an obsolete system. Removing it and having it re-cored is sage advice.
