Whoa, careful. ascari is looking for a MC that will fit a 101, while Jim G is discussing 105's. I agree with Jim G about 105's; I've done that same swap on my Sprint, using a '69 pedal box, but retaining the '66 MC. He's right, the bolt spacing is the same between those two MC's, but both were intended for 105's.I think it might be the same bolt hole spacing. My 67 Super was converted to the 69 pedal assembly. But has a single stage brake master cylinder on it. The 69 pedal assembly was a little different. As it was also the first year of the hydraulic clutch.
Or beg/steal/borrow a '69 cylinder - even a junk one - just to see if it will fit. Then spend $364 on a new one.You might email Classic Alfa and see if the will measure the bolt hole spacing.
Yes, I used to own a 101 spider, and recall that the MC was stuffed into a relatively small space between the floorboard and exhaust system. Even if the '69 cylinder fit into that space, its proximity to the exhaust might result in boiling the fluid.It's indeed a tight space between MC and headers
FWIW,I doubt that something like this will give you enough room,but the idea is there.Alfastop sells a pedal box spacer(easy enough to make,?)https://www.alfastop.co.uk/cgi-bin/psProdDet.cgi?prod_code=1BRM104 Also,I have an off topic question that you may easily be able to help me with.I have a master cylinder with 1" bore like all 2-shoe MC's,(probably 750 as it has the threaded endcap for the brake light switch),but the length of the mounting bolts would be shorter as well as the length of the master cylinders' mounting lugs.These lugs measure appx.1.845" long as opposed to most master cylinders which measure 2.25"long,a difference of.40".The parts book shows different MC and bolt numbers for the Sprint and Spider Veloces,SS and SZ than it does for the Berlina,Sprint,spider,and Ti. I've heard that the shorter bolt type is for the Veloce,SS and SZ.Can you post the measurements of your MC and mounting bolts?Thanks in advance,PhilThanks! On the SS there's even less space than on our 101 Spiders. I think boiling fluid may have been a problem even with the shorter MC since there's an intricate heat shield squeezed in between the exhaust and MC and bolted to the pedal box. Looks very original, but who knows? We're in rural VA, unfortunately not a whole lot of Alfas around here ("Alfie Romero? Who's that?") but if I snag a -69 MC locally I'll test fit and post what I find out.
My '63 Giulia had a heatshield too that I'm sure was built by the factory, but looked pretty crude. It was made from soft aluminum lined with asbestos.Thanks!

Hello Greig,I thought that the three shoe set-up used a smaller M/C piston too.Maybe they did after late 1961,but in my # N776,11/1961parts book,all internal master cylinder parts carry the same part numbers for all models,including the piston,main seal,etc..But even if the book is incorrect AFA internal parts,why the different part number for the mounting bolts? BTW,I totally agree with you AFA removing the whole pedal box for all of the reasons you've stated.
