Think the final drive was from a van not sure! Iv also got a bit mixed up its the iB5 box iv got in my car. I'm not liking the box iv got in the now, 1st and 2nd r far too long, wish it would blow up and Kames would be a good excuse to fork out and get a proper one made, still time though, British championship round in a few weeks, might drain some oil out of it (Joking of course). I was talking to the guy form Alpine Transmissions in Blantyre he said he could possibly build me a suitable box and his prices seemed fairly reasonable unfortunately I went to see one with the box one Saturday and the place was shut not had time to back, still going to visit him when I get a chance. Al keep you posted if I get any info.
