Brass freeze plugs.. are they really this difficult?

Anyone know what the official dorman part # for our freeze plugs are (96 L67)??

The GMPartsEast catalog says (part 129) that it is a 1.51'' diameter plug with .31'' thickness.

The guy at oreilly first sold me ones that were too small. Then he sold me dorman part# 565-029 (http://www.dormanproducts.com/p-7754-565-029.aspx) which is 1.572'' diameter and .38'' thick. I've had one hell of a time trying to bang this thing into the block. Seems like this guy did too (http://www.pontiacbonnevilleclub.com/fo ... gs#p318211). Apparently he went through 9 of them.

The next best thing I've been able to find (after parsing through dorman's ENTIRE catalog of plugs) is part # 565-028 or 565-828. These guys are 1.50'' diameter and .420'' thick
(http://www.dormanproducts.com/p-24239-565-028.aspx)

Did I miss anything in the catalog or is there a magic part # for brass freeze plugs for this engine? Or another manufacturer?

Update: Went with the 565-028.1 along with Aviation form-a-gasket. They fit the best despite not being a "recommended part" in O'reilly's database.
