Using old Ikelite ports on new Rebel XT housing

I have an Ikelite Canon F1 housing, with a dome port and flat port. I just bought a used Ikelite housing with no ports. Any way I can use the old ports on this new housing? I was told by Ikelite a while back that they will fit. I have the 17-85 EF-S lens, the 100mm macro, and a 50mm f1.8 (not macro).

The Ikelite port fittings haven't changed. I still use a port I bought for a film housing on my D80 housing.
