Disc Brake lower balljoint question

Hello, I have a problem with this disc brake conversion kit I purchased on eBay. I thought I could just drill out the lower ball joints to make them fit. However, the bolt pattern on the new spindles is 4.5 inches, while on the ball joints it’s only about 3.85 inches. Which lower ball joints do I need to order to fit my spindles?
