What you have pictured are not factory brackets.
They are some aftermarket manufacturers parts and pieces. They aren't factory Mopar items.
This picture may be of help to you.
A factory 73-76 A body sway bar, with all the mounting hardware.
Hope it helps.
Those brackets are for a 73 and up K frame. Swaybar goes threw the K frame. Those long flat brackets bolt to the K frame. The shorter brackets are used as spacers to help center the bar in the hole of the K frame. then the round brackets with the rubber pieces inside bolt on top. The L tabs go to the Lower control arm. some say bolt them to the shock bolt others say drill a hole threw the LCA. Since its a stock bar drilling a hole threw the LCA will probably work the best. Unless you have factory sway bar tabs already on it.
thx guys so they are wrong for my 72 k-member now i know :-Di i just was wondering why they dont fit its complicated somethimes when u have a mixed front suspension 72 or 73
