3015145 is the old part number but it's been replace by GM's imported version of the heater core!
P/N 3015145 was replaced in August of 1999 with new number 52484060, this number shows being no longer available too! I'm not positive about this I'll have to check.
I have seen post in forums where people reported problems with the connection of the tubes to the core.

Mike, if you buy a new heater core, take it to a radiator shop and have the tubes re-soldered and the core pressure-checked. Learned this the hard way when the interior of my 68 started filling up with anti-freeze after installing the heater
Good thing the carpet wasn't in yet

Yes my 1974 has A/C. I did that job in 2008 and do not wish to do it again. I figured that AC Delco/Made in USA would assure some quality for the core. I was rather shy about those $30.00 Chinese units on EBay and I was willing to pay the Delco price. I may be proved wrong on my approach but so far so good.
If I remember the GM unit was about $80.00. But what price is your labor worth if the cheap imported unit fails prematurely?

I'm thinking the same thing. I ordered a GM unit but will still take it for pressure testing as Randy suggested. Too terrible of a job to want to do it twice.
