peddal box supply or group buy?

Here's the master cylinder I have, it came out of a 1993 1.8 CVH CFi. I tried to measure it and it looks like roughly 41mm but it's hard to be sure as the bit at the top isnt the same as the bit at the bottom so to speak. If possible I would prefer the throttle in 5mm as well as the brake & clutch. I know it's probly overkill but it'd be a right pain to remake at a later date if it bent / broke.
