S40 braze-on FD question

Hello,
I'm starting my S40 build and sourcing parts from my old bike, but it has a clamp-on FD. I'm unfamiliar with braze-on's. Will all braze-on FD fit the S40 or is there a specific braze-on mounting size that fits ?
thanks,
Kenneth

You get a braze-on FD which is compatible with your left shifter. SRAM and Shimano don't mix; Shimano and Microshift may be OK. A braze-on FD may work but not too well on compact 50/34 chain rings.
