To use the S-10 ball joints you'll either have to use aftermarket control arms made for them or modify the OE arms to accept them. The S-10 lower ball joints have a much larger body, but UB Machine makes weld-in sleeves. The uppers have a larger bolt pattern but other members have had success in modifying the control arms.
If yours is a '75 you should already have the correct ball joints to use the V8Monza.com adapter sleeves to fit the S-10 spindles.
