I'd recommend getting the stalk (and loom if you need it) from Jamie at Sopers Lincoln. Mention you're from the forum and he should do you a discount. Excellent service, and the Cruise Control fit is a doddle!
My TR6 has it on 2nd 3rd & 4th a very worthwhile addition .So much nicer than the the 5 speed after market box that can now be fitted as an alternative. It just seems to suit the the car better.
