Dug around today and found a spindle. Not sure if it's a genuine Lc rear wheel spindle, but diameter is correct and length seems correct. I haven't got another to compare it to, but the length, and the thread length seem correct for the Lc swingarm;
Cheers again Dusty. Made a LH spacer 6mm thinner, RH side I took off 5mm so can take another 1mm to even it out. I have 204mm between the insides of the swingarm, but with the adjusters, the the total measurement is 230mm, so I still need to lose some more!
