Many (all?) libertarians lean left on a great many social issue and consider the social part of libertarianism as important if not more important than the right leaning economic part. I think the term "libertarian right" while not an incorrect term at face value -- there are in fact right leaning Libertarians just as some Democrats are further left than others -- is miss-leading and can potential lead to misconceptions about Libertarians as similar to Republicans. I for one share much more in common with the Democrats but I am very definitely a Libertarian.
I think many of us would prefer you just use the term Libertarian and leave off left or right.
Edit: or perhaps if you were in-deed referring to the conservative party, add some clarity and say "Republicans that lean Libertarian"
