Lower control arm pin/bushing install

Been fighting with getting the pin in. Unfortunately bushing already in. Yeah the ball joint press is just a smidgen too short. Been rackin my brain trying to figure out a way. Need something that will slip between the shoulder of the pin and the press. Getting frustrated need a shop press but no money. Don't know anybody who has one either. I've got a bottle jack but need some kind of strong frame. Anybody got any ideas? Still have the other side to do and have to get to work on Tuesday. Wasn't expecting this to be such a PIA!!!
