That IS what I was asking about but "150" is a little vague, and based on experience you won't have much wiggle-room to fudge with headset stack heights, so...measure twice or even 3X to be sure.
i probably have a chrome fork that could work, but won't waste your time until there's a certain number (like a steerer length/height or headtube length/height) to work with.
