Coupler pin removal

I just bought this:
EZ Red PPT13 Roll Pin Remover for Clutch Cylinders & Hydraulic Clutch Lines | eBay

I have seen it but never could find dimensions, I need to do the same to replace my firewall seals, and repaint the firewall around the MC / stearing column.

I'll post what I get. If it is too small for stearing coupler it might work for the brake handle easier than my home built press.
