Audiolab8000M smoothing capacitors

My English made Audiolab8000M mono amplifiers are at least 25 years old and I am thinking about replacing the 10,000uF smoothing capacitors. I just want to find out what the physical dimensions of the factory fitted capacitors are without trying to measure them in situ. I have a few possible contenders for the replacements and Mundorf mlytic ones seem to be suitable provided they are suitable size wise. If you have done a replacement recently could you help me by measuring the old capacitors ?

If so, I don't see what your difficulty of measuring in situ is.
