As a final item to this post, I’ve gone with grinding two grooves for the bolts in the new stainless spindle, and voila (with a bit of cursing getting the brake plate position and two grooves lined up) = one front wheel back on correctly.
All I need now is for my Speedo to come back from Ashley at Speedorepairs……I’m assuming it’s going to be a top notch job judging by the time he’s had it (end March)….
