Forgive my ignorance ...
do the shift stablisers fix the 'saggy shifter' problem you get with the gear stick not having much resistance when you push it left (1st and 2nd)? The shifter in my car has this problem, you push it right from neutral and it's real stiff, but when you push it left it's not stiff at all (probably because the majority of shifting is between 1st, 2nd and 3rd)
