I went to my local breakers first, they had one GTE in the whole yard which happened to be a cabriolet, the digi dash and sender were gone. Then i tried the other backup breakers yard, they had 2 there. One was another cabriolet which had a sender and dash intact but the sender had the AH identifier, no good to me. The other one i found was badged up 2.0 8v. Whipped off the sender and it was AK, reeeeesult.
The poor soles probably didnt even know what i layed before them at the front desk, after a bit of a wheez and word with his even wheezier mate, the reply was "3 quid mate"
I screwed my face up in a mock fack-me-i'm-getting-raped-here pose, and then handed over the 3 quid and did a runner before they realised.
plugged it in on their forecourt and voila, we have speedo. Shwweeeettt.
Apart from my find, it kinda confirms i have a 8v dash and sender, must have carried them over to the early 16vs.
