Dowel pin on Steering coupler size

[Challenger RTA]

getting the main pin out of the coupler to disengage it.

You need one of Theis and good drift pin. Using a 5/16 or 1/4 drift pin don't remember what size. With the steering box off. Take the coupling apart to get the steering box out. Place on a hard surface to drive the pin through.

I'm in the process of removing my column to do a refresh/ rebuild and replace all the internals and bearings- but we are having a baad time getting the main pin out of the coupler to disengage it.
Ideas?
I'm probably going to replace the coupler (all internals). If we can't get the pin out, would drilling it out be a solution?

I had a rough time with mine. I soaked it with Free All for a day or so and then used a pointed chisel and beat the crap out of it with a big hammer. Good luck!
