R & R leaf spring bushings.

I have never replaced the leaf bushings on my 68 Barracuda, and am seeking advice on the the best shadetree method to remove and replace. I have a set of Energy polyurethane bushings I plan to install. On the internet, I have seen torches, BFH's, and drills used in removing the front bushing. Has anybody made a homemade tool to do the the job, such as maybe some c-clamp contraption? Once it is out, will a new one push back in with a rubber hammer?

Thanks, Scott
