I'm looking for a Jones unicrown fork with the 135mm spacing so I can swap out my truss fork and give myself some space for a dog basket up front. Ideally need about 250mm of steerer.

Thanks in advance!

Can't help with the unicrown but if you were selling the truss I'd be interested, got a Jones needing a few fork. Cheers,
James

Think I'll keep hold of the truss in case I swap it back on later

No problem, I would too!
