VS manual computer

[Nastas]

Just wondering if there is a difference between the computer and loom used in a S1 or S2 VS manual.

I am about to do a manual conversion on my VS1 with a T5 and would like to get a manual computer but can only find them for the VS2 with the getrag.

Any ideas?

Dont want to fork out hundreds of dollars and then find out theyre different
