If you buy a NEW Behr radiatiator the fact is you won't be getting a similar defective part. The OEM radiator on my '91 had an UNREINFORCED upper hose neck (I assume yours on your '92 was similar) and I opted for the peace of mind and bought the new radiator with the reinforced hose neck.

You could engineer a repair on the one you have but if the original radiator already has 75,000-100,000 miles on it it could be considered a consumable item and you could simply replace the whole thing. I personally don't care for the risk of a quick catastrophic failure...
