custom trailing arms for 14 bolt rear-end installs

[old crewcab]

Ok guys, need some input. Unless these already exist, and I just don't know how to properly "search", does such a trailing arm exist? I know you can get the brackets to weld on, but I would think there surely would be interest in just "bolt on" arms. Bolt on in front as usual and rear would mount where the leaf pack was. Easy enough for for weekend warriors as a option without the need for welding and fabbing. Reason for asking, thoughts in my head of a 65 c-20 with 14 bolt cab &chassis rear would be neat. The narrower width would give better wheel options.
