Swapping a deep-piston in a shallow-piston MC
I'm in the process of fixing up a '74 c3, I already put the Wilwood alu calipers on it only to notice the original? master cylinder was leaking from the booster seam.
I took it apart and it's pitted a bit too much for just some honing to fix it. I started searching for master cylinders and noticed they make aluminum versions.
Wilwood make one, but it has the wrong size outlets so that's out of the question.
SSBC seem to make 3 different versions, of which the direct-fit 0475 seems to be impossible to get, so I started looking at the 0477 which is for 77-> c3s with a shallow piston which wouldn't work directly.
Can I just swap in a deep-piston from an older rebuild kit or are there some other differences between the master cylinders that means it won't work? I already have a brand new rebuild kit so it wouldn't cost any extra.

I ended up ordering the Ssbc master cylinder, saves me some money if nothing else.

Anyway, I ended up ordering the Ssbc 0477 to which I will then just swap in the deep piston.
