Early Vs. Later Lower Ball Joint Issues

Started ReAssembly today on the '65 Barracuda Front-End...
Realized pretty quick that the Holes thru the Lower Joints were an 1/8" larger than what came out. I guess Replacement Parts are all the Later-Style Disk stuff?
How can I Overcome this with what I have?
1/2" bolts thru the Spindles and 5/8" Holes thru the Ball Joints...
That's Alot of Real Estate in there, Should I Drill Out My Spindles and Replace the Bolts?
