Homemade Adjustable Strut Rods?

I talked extensively to my alignment guy about this same thing a couple weeks ago, he said he has done this with the aftermarket ones, and it actually causes way too much positive caster. His advise to me was leave it alone, unless you are road racing a car, there is no advantage to doing this. As is normally the case ma Mopar had it right from the factory. I'm no expert by any means, but my alignment guy races a big block dart, and know's Mopar A bodies pretty good, I trust his opinion on this.
