Eliminating Quad shocks

[Chrispbrown36]

I have read a few times on here that people recommend going from quad shocks to duals up front because of ride quality. I would like to change over simply for economical reasons.....shocks aren't cheap and 4 is better than 6! I searched the posts but couldn't find anything specifically about doing it. Is there anything special that needs to be done or can I just take off the four and use the existing mounts to put two new ones on?
