Got a set of these. but they used a different type of wheel bolt consisting of two parts. Where can i get a set of these 'special' bolts?
Those bolts are utters pooe. The stud on the ones I had would not come out of the discs when I wanted to put my steels on. I would try and see if you can get something else.
I got a set of senekas on mine: http://pic5.picturetrail.com/VOL91/1369296/2606138/31654421. jpg so I take when you say 2 part you mean with a longer unthreaded shank of the bolt. If so, you wanna go to somewhere that sell Jap alloys. You'll also find that they use the small Jap size valves too.
