A Body Sway Bars

Can anyone tell me where I can get a front sway bar for a 1970 Dodge Dart with aftermarket QA1 lower control arms installed? I went with PST and ordered their sway bar and found out it's too long and won't connect to my QA1 control arms. When I called PST customer service they said the only way it will fit is if I go with their K frame at $600+ cost.
Any suggestions for me?
Thanks
