Thorn's "steering lock" should work provided:
a. you have >10mm of headset spacer on a 1 1/8" fork steerer tube to permit striker installation, and
b. your headtube has >10mm of extension above toptube junction and an OD of ~37mm to permit limiter installation. You need striker and limiter parts for a complete "steering lock". Make sure all fasteners are included since they are probably not a stock item at the Local Hardware Store.
Headtubes with 37mm OD are typical for steel frames designed to accommodate forks with 28.6mm (1.125") steerers. For example, the Thorn "steering lock" will fit a Surly LHT/DT (28.6mm steerer/30-40mm HT extension/37.3mm HT OD).
Obviously a velcro strap, mini bungee or paracord through the wheel and over the downtube will also immobilize the fork/wheel/rack/luggage, saving ~60g and $60. I prefer the simple/cheap solution in this case.
