Please explain the difference between the 10-19 master cylinder and the 10-20 model? You say they are similar but the ports are different?
The difference between these two are, P/N# 10-19 has an install length of 8.35". The port size is 7/16-20. The comments are, "Ports in-line, fittings 90 degrees, extruded aluminum body".
P/N# 10-20 has an install length of 7.48". The port size is 1/8-27 NPT. The comments are, "Ports in-line, no fittings, no rod celvis, extruded aluminum body." These two are not interchangeable with one another".
