ISO NOS part
 

Part number 19121-MM5-000.....upper left coolant hose.....goes from radiator cap housing down to the upper left back of head. Have done the Google search, but no joy....like so many other parts for an '87, it's discontinued...anyone know of a reliable source?

Thanks,
Jim

Would you consider a used part off e-bay?

Already have a used part...LOL! If it's in good condition with no splits, etc. Of course, prefer NOS. You have a link?

Thanks! I'll check it out!

Don't know if 88 is the same, but here are some used ones on ebay.

Sorta like buying someone's used tires, isn't it?

I would also go with new, even if not OEM.

I'm told that if you bring the old hoses down to the local parts store there's a decent chance that they can find something similar off the rack. Might need trimming but it's better than nothing
