Default Master Cyl / Power booster Rod length

Does anyone know about the length of the rod that goes between the master cylinder and the booster? I have four different rods here and the length differs by about .035. All are in the 2.590 to 2.632 range.

Here is why I am asking. A LONG time ago I purchased a rebuilt booster from a company called ASL...Resto House now outta business. The deal was an exchange my old booster as a core to be replaced with a new rebuilt unit. I installed the new unit and had issues with pedal travel. Called ASL and was advised that there were "several" different length rods for these cars. According to my memory I was further told that the correct length was the length that worked with any particular set of components. Factory tolerances and what not...same thing as the shiming of a pinion depends on the dimensions of the gears and the dimensions of the housing. Factory tolerances. I got 5 or 6 different lenth rods from ASL and got the brakes working correctly with one of the rods. I saved the others. All the rods were around 2.590 / 2.630 inches.

Research here with the search function mentions two distinct lengths for this length is around 2.6 and the other is way longer. My questions is related to small differences in the lenth of the 2.6 inch rods not the differences between the 2.6 and 3+ inch rods..

Has anyone ever heard of this small difference in lenght requirement? Remember I had a problem and I corrected it with another rod. The difference between the rod that did not work and the rod that did work was a very small amount NOT a distance of an inch or more. All the info I can dig up relates to length diffeerences of over an inch. I am talking about a much smaller length change fixing my problem.

All this has come up because my friend has an issue with a disc brake conversion and I am wondering if his issue is related to an incorrect length rod between the master and the booseter. His brakes work BUT they don't work well...long story. Before I go there I want to see what I can learn about smaller differences in length of push rods that are in the 2.6 inch overall length range.
