Booster Check Valve Identification

[doubleyellow]

Is this the correct check valve for 1970 e-body with 440-4 and power disk brakes? I've also seen them with only 1 port. Thanks

I think it is the correct one for the Midland Ross booster.

I think the Power Disc Brake Master/Booster is Kelsey Hayes, right?

Not sure who made the master cylinder but the flat pancake booster manufacturer is Midland Ross.
There is another type of booster but cannot recall manufacturer.
Kelsey Hayes do make the "PIN" style caliper I know that for sure.
That master cylinder may be made by Bendix.
