Ray - I've been enjoying your thread for awhile. I'm on the tail end of rebuilding a 1978 R100/7 and just went down this path. I thought about saying something when you reached the point of setting the end float on the cam (I had to go back and pull mine out, too), but didn't want to discourage you and was hoping you would find a better way! I just thought I'd jump in at this point since I do have a resource for those clips and many other metric fasteners at http://www.mrmetric.com/ and here is a link to the e-clip - http://www.mrmetric.com/metric-fasteners/metric-e-rings-steel-m2-3/ I have no relationship with Mr. Metric other than satisfied and repeat customer. You can buy single fasteners from them and the prices are great. Shipping is a flat $6 for USPS priority on orders up to $50 and free above. I've made quite a few orders to them as I've been doing my restoration. I hope this helps you and others out. Keep up the great thread. This is fun to watch!
