I had this rad in my 71 blazer for approx. 1.5yrs. 2 days before I moved to Flagstaff it developed a leak.My local rad shop said it would take two days before he could even look at it. I called radiators.com and had a new one the next day. Anyway I held onto the old one so I could get it repaired. I had a leak at the filler neck and drain spout. I had it repaired at a local shop here in Flagstaff. He repaired the 2 leaks,pressure tested it and repainted it. He said "the core is in real good shape!" $80.00 (FIRM)plus shipping from 86001.
