front view rear view another viewI don't recall now what I was asking for it, but I know I based the price on the price of a new core.
And just for the record, no, I'm not trying to sell it here.
One last thing - I thought that I had the heater core flushed and cleaned at the same time that I had the original gas tank done, but it doesn't look like it, so maybe I didn't. I just don't recall now. I suppose I could scrounge through my receipts.
I ran the heater for a few years after rebuilding it, and it worked fine, didn't leak, heated properly, etc. I removed it when I installed the air conditioning this year.
