In the stage of making up some mounts in my 120y for the gearbox and engine (L18 and sss stanza 5 speed). Where i want the engine to sit the electronic speedo sender will foul on the original gearbox mounts that are on the trans tunnel. I am wondering what i can do to get around this or what are some alternate speedo options I could use. I have seen on autometer etc speedo senders that you run off the tailshaft etc. What are your thoughts?
