Hi Craig.
The better package as far as Which Kit was the silver one. This had 15" and 195 rubber.
As far as the speedo, I bought one of these to convert the speedo.

But never used it due to me converting the gearbox speedo. Converts vertually anything to anything using electronic speedo signal. Let me know if it's any use to you.
