LARES 8015 Remanufactured (part number listed on Rockauto.com - not available)
Manual Gear; 1/2-2T; Exc C O E
LARES is the biggest steering gear rebuilder.
But, they might need a "core" unit to rebuild.
Many companies list this unit, but they do not have it in stock.
Post a Part Wanted ad here - as VEW posted, a member/reader might have one laying around.
