Brake conversion. Lower control arm swap?

Lower control arms without sway bar tabs are the same for 63-76. The sway bar tabs that are located out by the lower ball joints are 65-72. Tabs located 4/5 inches away from the ball joint are 73-76 and are used with the 73-76 sway bar which does not fit the pre-73 K Frame. It appears you have the 65-72 style LCA’s which will work fine with the disc brake swap. I’m using the 73-76 disc conversion with 65-72 LCA’s with a sway bar
