I upgraded to a 929 cylinder. Bought from Chips, direct bolt in with zero issues:

I recommend adding a master cylinder brace. I had a small spongy feeling that just wouldn’t go away no matter how much I bled the system or adjusted the rod. After adding a brace it instantly felt firm, so I guess the firewall does flex a little.
I got mine here:

but I see Sakebomb etc offer them for LHD cars too
