I have to wonder how close the 73 74 charger rear sway bar bracket is if not the same as the the later years like yours. The strap part number 3402897 listed in the pic I posted is the same as 73 up b body. https://www.hiltopautoparts.com/pro...iner-1973-4-b-body-1972-3-c-body-models/ You could weld a bolt to it if you can`t find one. The replacement kit 4106151( if you can find one) is a bolt on type not like the OE that looks welded.
