What can i do to make the speedo on my 1200 ute work with an r31 stumpy gbox...stock diff too.
Thanks in advance

I think you only need the speedometer cable with the larger end on it. Cable from a 610 (180B) will work.

200b cable works in mine, so does 120y in Andy's I think.
I paid $50 for a new one custom made longer by speed screen in Melbourne.

They need the ends off the stock ones sometimes to match them with new ones

I use the 120Y speedo cable and housing with the skyline stumpy, works well. It's a tight fit in the tunnel but just fits with a bit of massaging.

kool, so the 120y is direct fit?

R30 or r31 gearbox. the actual stumpy box is an r30 box. and the speedo output is on the left hand side of the box....and from my experience a 120y cable will not be long enough unless its routing it very direct which would not be the neatest

i ran a 200b cable and it was the right length to run down the chassis rail and then wrap under the gearbox to the sender

with my r31 gearbox (non stumpy) behind the CA i use a 120y cable as it doesnt have to cross to the opposite side of the car, assuming it is a right hand drive vehicle, and is therefore the correct length as it is from memory about 150mm longer than the 1200 one

r30 stumpy.

200b cable

if its not accurate you can get corrector boxes to make it right
