Hi, I would like to know what is the distance between the two centers of wholes where I would insert the bolts to install the part. If you have in inches and cm that would be great. Thanks!
The center-to-center distance between the bolt holes is approximately 3.38 inches.

Does it fit 1978 cj5 4.2L without brake booster with disc brakes in front and drums in rear 11x2 rear shoes
The Crown Automotive 83300111 Brake Master Cylinder is specified for 1978-1986 Jeep CJ models with power disc brakes and 2-bolt calipers.
Your 1978 CJ5 4.2L has front disc brakes and rear drum brakes, which matches part of the requirement. However, the crucial factor is the lack of a brake booster.
This master cylinder (83300111) is designed for systems with a power brake booster. Using it without a booster will likely result in:
A very hard brake pedal: You'll need to apply excessive force to get the vehicle to stop.
Reduced braking power: The master cylinder's bore size and internal components are calibrated to work with the added pressure from the booster. Without it, the hydraulic pressure generated by your foot alone might not be sufficient for adequate braking.
Potential safety hazard: The vehicle may not be able to stop effectively in emergency situations.
Therefore, the Crown Automotive 83300111 Brake Master Cylinder is NOT the correct part for your 1978 CJ5 4.2L without a brake booster.
You need a brake master cylinder specifically designed for a manual brake system (without a booster) with front discs and rear drums.
