Will be refinishing and profiling a LS3A this winter. Need the wing profile
data which manufacture will not share.
Does anyone out there have tha data they would be willing to share with
me?

Careful about free advice! It ain't just about waves.
The 67 series is very sensitive to correct profile on the leading
edge.
A few measurements should show linear taper root to tip with airfoil
doing the same thing.
The bad news is that to make templates , you have to plot the airfoil
at each station interpolating between the 67-170 and 67-150.
You don't really want to know how I know this. It's painful.
Look up the series Dick Johnson wrote on improving the PIK-20 which
uses the same series airfoils.
There is much to learn in these articles.
Good luck
