Procomp roller rockers

Hi all,
i bought a set of procomp roller rockers off ebay. these seem like really nice rockers with needle bearings and all. Unfortunately the support I'm getting from the ebay dealer and procomp are not very good. Here's my problem. Stock push rods for hydrolic are ball end at both ends. the new rockers have an adjuster with a ball end, so obviously I need a ball and cup style push rod. I'm not sure where to get, or what to get that will fit well, and when I do, what's the sequece of events that i need to follow for setting the correct adjustment. I have a 360 small block with Hyd. lifters.

Thanks,

Stu
