New Door Bushings for Chopped hinges?

I cut my door hinges the other day on my 98 4 door. I am ultimately planning on cutting the bottom ear of the Door side of the hing off and welding a bolt top and bottom so i can lift it on and off like shown here http://www.jeepforum.com/forum/f11/another-idea-going-doorless-97-a-444398/index5.html . Right now i am just using 5/16 bolts at the hinges and its really not that difficult to get the doors off, getting them on requires two people however.

I need some new hinge bushings. Obviously the Inner Diameter i need is 5/16 im not sure of the O.D., however can I not just by new JEEP hinge bushings? I assume they are made of Brass. It would be nice to be able to get oil impregnated bushings, that way i can fix this door slop ive had, and they would e easily replaceable/smooth operating

thanks

I used tapered pins for mine. Different hinge style, but if you could taper the bolts it should get easier. 2dr doors by yourself... now we are having fun!

i'm wanting new bushings to fix door slop. My pins work great, Im just looking for new little brass bushings like the factry ones
