How to remove and install new Lug Studs DIY

[hotwls13]

Picked up some centerline wheels this weekend on my way down to Pomona swap meet this weekend. Tried installing today and my studs are too short. Anyone have a diy method to remove old studs and install the new longer ones? All while leaving rear axles installed as well as doing the fronts (drums all around).

Been shopping for studs and they are about $2.50 a piece so $50+ for 22 of them (6 bolt hubs and 2 of the driver rear studs have already been replaced with longer studs).
