Oil Pump rebuild questions - How to?

[Nosetime]

Hey guys, I want to rebuild an oil pump. Everyone sells the kits, but is there a tool to press out the old bushings? I only find the reamer at Brattons and nowhere else? Is the bushing driver for distributors also used for oil pumps. Finally, it would appear the first bushing would be driven all the way down - to then push out the second bushing, is that correct? I find nothing in books or online describing oil pump rebuild procedure. And finally, for those in the know, would the driver and reamer also work to rebuild my B Distributor? Would be great if the tools will work for more than one job! Thank for any help. Greg
