KCA nozzles. Are they interchangeable?

[67gtman]

There are some 15 nozzle types for about 10 KCA-type bosch injectors. Do these nozzles have same dimensions and can be physically fitted to any kca injector?

[sgnimj96]

probably,  but the IDI vw's only used 3 different types afaik
dn0sd293 was the most common,  193's are about the same but were from the early 1.5's.

Using the wrong nozzles may not make a difference,  but it won't help.
