That pin is fun...
Slide hammer wont fit... no space.
Find a bolt that fits the internal thread, find a long socket that is larger than the giude pin... Crap, was gonna use words... but here is a pic that will make more sense...
One socket, a bolt, and some washers or a nut, or both...







Thread the bolt into the guide pin and tighten... it will pull up againt the socket.... the little sucker will come right out!

The socket, bolt and nut/washer may not be what fits... I dont remember which ones, but thats how I did Ps2cho's pin(Im his Dad).
I think you can grasp how this works...
