please use the buchillion setup instead. you will be happier with it.
my opinion on the lokar is not good.
i have changed over a dozen lokar setups back to the factory or the buchillion. lokar is just a "fitzall, hope it works" GM adaptation that uses cheap, bicycle type cable and somewhat flimsy brackets.
as the cable stretches, you will be constantly fiddling with your adjustment.
just my experience and opinion. your mileage may vary [but i'm not the only one with this opinion]
