Bump stop removal/replacement??

I have an 04 5-lug and I put 1.5" coil spacers on it a few months ago. I didn't really realize that they would affect travel in the suspension until someone on CT mentioned it. So I was thinking that I might could get a little bit of travel back if I put shorter bumpstops like these on http://www.energysuspensionparts.com/prodimages/Energy_Suspension/99102G_lg.jpgbut I just looked and the factory bumpstops are one piece of rubber that pulls through. I don't want to risk tearing it trying to remove it until I have some more to put on. Will the ones in the link fit and replace the factory ones? Here's a pic of the suspension to show how much travel I have

I labeled the two bumpstops in the pic. Would replacing 1 be ok? It doesn't seem like 2 is the one thats limiting the travel and it looks like its alot bigger/more important so I probably don't want to replace that one right?
