throttle cable removal on an 88 lx 5.0

[c3racer2000]

I bought a bbk throttle body for my 1988 LX 5.0 mustang. I can't figure out how to get the throttle cable off of the old throttle body. This thing is made of plastic and looks very easy to break. The cruise control cable just popped off but the throttle cable goes through a nylon groumet and I"m afraid to try prying it off. There seems to be a piece that allows you to adjust the length of the cable under where the cable attaches via a peg to the groumet. I'm sure a lot of you guys have replaced throttle bodys and this must be fairly simple but I"m stumped. If anyone can tell me how to remove this cable I'd appreciate it. Thanks
