I fitted an ep82 one on my ep70. I had to weld some extensions on the end of the bar. So that you can bolt the drop links on. Ran that for a while till I got hold of a GAB 24mm one
Think I only had to move a couple of wires for the indicators and couple of the dash light wires. Also added an earth for the elimination lights. Was really simple following the tracks on both clusters
Nothing wrong with alloy wheel nuts. I'v taken loads of wheels off and on with them on. No problems at all. It's just the idiots who tighten them up without a torque wrench!
