Midland Brake Booster

In need of a Midland brake booster for a 73 Duster with front disc/rear drum. Midland has a clamp ring around it and Bendix has a crimped housing.
Thanks and be safe out there, Jack
I have a booster I bought for my 69 Barracuda but turned out to be too big in diameter (8 1/2 - 9"). It has a clamp ring around it.
