Have a look at this guy's site, he seems to know a lot about Bonaldis and suggests improvements (scroll all the way down):

The brake master cylinder on your exploded view is the same as the FIAT 850 Spider one – except the later has two holes where the Miura one has only one. At EUR 19,50 it is a steal...

Here's a link for the original FIAT 2300 master brake cylinder at EUR 480,00 (FIAT numbers 4110334, 4105671, 4127548, 4183029):

However, the same dealer sells the same master brake cylinder for a FIAT light truck and claims it is the same as used in the Miura at EUR 90,00 (FIAT numbers 4396082, 4334273, 4295012). He also mentions that the original cylinders in the Miura were made of aluminum:

If you look closely, the FIAT 2300 cylinder seems closer to the original shown in the exploded view of the spare parts manual.

Miura pedal system

Pedal bushings BCN-01972 2ea and BCN-01957 1ea in early Miura were a piece of poly plastic, probably Vulkollan flat stock cut to size to fit each pedal. The accelerator and brake take the same width and the clutch took a wider piece. This poly material fails and comes apart, jamming up the pedal movement.
The Miura builds switched to metal backed split bushings during the S series. Two of these MB1815DU split bushings were installed in each pedal pivot. The construction of the bushing is carbon steel with a PTFE inner surface.

The part number MB1815DU, with MB as metal backed, 18 as 18mm shaft size, 15 as 15mm width, DU indicating a Glacier brand split bushing.
