Lee is absolutely right. Once I got the seat mount out, I didn't think it was too hard to get the subframe mount out. But, there are ALOT of welds. That job took me more time than I thought it should, and a person really needs a good bit of patience when they are doing it as well.
You're probably already doing this, but using something to pry the mount up while trying to locate the next weld is practically mandatory. I think Eastwood sells a tool that looks kind of like a cake cutting knife to separate the panels while disassembling. It looks like it would work well, but I just used whatever I had around here--probably a big screwdriver or something along those lines.
