I've been getting to know my new-to-me '74 R75 for a couple months now. The PO's parting words as I rode away were "you should get some new shocks on there ASAP". Boy, was he right! I installed a set of Ikons and it's made everything feel much more planted. I did, however, discover that he had used a non-OEM bolt in the lower left shock mount position. It's part # 33531230249 and it's no longer available. The bolt he used is short enough that the nut only grabs 4-5 threads and he didn't use a nylock nut. This being a fairly important spot to be well tied-together, I'd like to get the right nut and bolt in there. Anybody know where to find one? Motor Works UK has them listed used on their website, but I'd like to get one from closer to home if possible. The impression I've been given is that I shouldn't use anything but the OEM item in this location. Is that right?
