The later A65's used a standard distance piece 68-688 with a thickness of 0.295" (TBC) + shims of various thickness (40-66 10 thou, 40-69 15 thou).

I need two 68-0886's and I have managed to get one.

From your information I have decided to get a 68-0687 which should be okay as it's around 6 thou larger, a bit of fitting should do the trick.

Thanks again...
