Here's what worked for me, others may have a better way. Also, the description of the pin is appropriate for my setup. Don't know if they are all the same.
You have to first drift out the cross-pin. Look at the ends. One will be solid, the other sleeved. Push the pin out from the sleeved end with a drift pin that contacts only the center, not the sleeve. It will not go easily.
When the pin is out, the two plastic cones will fall out revealing a hex nut that secures the latch handle to the sheet metal of the hardtop.
If you irrepairably screw up any of the parts, Bud's Benz has a kit that includes everything but the handle for about $80.
Good Luck, Gus
