Rock Chucker disassembly.......?

[3006guns]

I've just aquired an early (1970's) RCBS Rock Chucker. I need to disassemble the press, but I'm stuck on one thing. The lower toggle appears to be a pin with a nut to hold it......fairly obvious.....but the upper pin is flush with the link arms and in line with the ram, so it must be two pins. Has anyone taken one apart before? Sure could use some pointers!

Edit: Do you remove the lower pin and then slide the link arms off the upper pins? Could it be that simple?

Looks like the top has two pins...unsure if they are blind pins or if you can tap them straight through.

I believe you take out the ram and then drive the pins into the ram hole and they fall through.
One more thing on the old RCBS Rockchuckers the date of manufacture is stamped on the top of the casting near the die hole.
