hello guys i'm new to the forum, but not new to A body mopars. My current A body (66 dart style, canadian valiant) has manual drum brakes and I think I found a brake booster for it but the person doenst know what its off of (obviously mopar though) so i'm wondering what the width across one is from side to side, also the length but thats not as important

Many different brake boosters were used on A-bodies. Diameter and depth depend on year, brake system type (disc/drum or drum/drum) and whether the power brakes are factory or dealer installed.

Now that I think about it I am pretty sure I have a complete A-body factory drum brake booster/brackets setup on the shelf; send me a PM.
