Ok guys what do you have on your Mustang II front ends in the way of sway bars ?

Putting together my 40 Ford p/u front end and I have no sway bar. Does it make a difference, I'm thinking it would but I don't have any past history to base that on.
Who makes a good after market one or can I get one off a car at the local Pic n Pull ?

Thanks again.
