Hi all
I am getting to the wiring stage and I am wondering what dash cluster to use. I have a rover v8 engine and manual box with sierra back axle. I do
not know what the diff ratio is. It came out of a 1990 1800LX. Should I use the sierra one or get a rover one? If so which one and what speedo
drive cable do I need?
Thanks
Have you thought about a digi dash? Gte some fairly cheap ones nowadays and then itll all be new stuff and look a lot better IMO
PS. where abouts in lincolnshire you from?
get an electronic speedo from someone like ETB instruments. they can then advise you on how to set it up with your wheel/tyre/diff combination 
I would also have to recommend one of the various digital dash displays. Something like the Acewell should suit your needs really - unless you prefer
the classic style guages.

These should make life a whole lot simpler to ensure calibration - especially as you dont know the diff ratio. Saves having to route a speedo drive
cable also as its a sensor / magnet on the prop etc
i bought some RMD instruments from rally desing and they're top quality and cheap too. i forget who they're made by, but they're good
