944 to 1303 hand brake assembly?

[Maynard]

I purchased the Kerscher parts for the assembly of the emergency brake for the 944 conversion. Since the parts I got came from a 1985.5 944, I will be using the Al trailing arms.

I understand the 944 ends will have to replace the VW ones. Do I cut the VW cable as long as possible or do I have to determine correct length to cut? If that is the case, how do I determine the correct length?

I don't understand how the tubes are used with the Al arms. Is this only needed on the steel trailing arms or how do I use them?

Thanks for the help!
