73 E body front disc brakes conversion on A body. Where did I mess up?

Good luck .
Thanks for suggestion. Just going to do without sway bar. Saves me $500.00. Control arms (with tabs), if you read entire thread, has been a hassle. My originals (w/o tabs) are painted ready to go. Could order different lower ball joints but that would be Moog and who wants that.
