I know it's like I'm talking to myself here, but this might be useful in the future if someone else has the same problem.
While trying to cross-reference some part numbers, I found some Raybestos numbers at Rock Auto which appear to the proper ones that I removed:
RAYBESTOS Part # 5701076 Front Lower Front
RAYBESTOS Part # 5651213 {#5701075} Front Lower Rear
Then I found this thread on FSC, This guy has the cast lower arms and the same problem, he found the Moog part K6687 (Off of a Hummer) and said that they pressed right in and work just fine. I'm going to track down a set and see what happens.
