Hi everyone I have recently come across some special tools on eBay sold by a guy who used to have a dealership. Sadly it got shut down in the 80's as I understand but he kept a lot of special tools in storage including the 5188 wrench I have linked to here. The listing says he's in Alberta Canada which makes postage to me in UK overly expensive so I've linked here hoping they will be more accessable to some you over in the states or indeed Canada. These are not my tools or listings but he seems like a nice guy so drop him a message if you need anything in particular and he might just have it.
