well i finally recieved my hotchkis extreme sway bar set the other day and was very eager to put them on today after work. i ran into a hell of a speed bump though. i have waited to buy my sway bars so that i could get hotchkis' new extreme rear bar. what they fail to mention in anything that i have read is that in the directions (believe it or not i read them ;) )one of the first things it says is that this bar will not work with stock control arms due to clearance problems. i was going to just notch the side of my factory rear lower trailing arms for whatever clearance i needed but realized the hotchkis lowers also apparently have holes in different locations than my stockers. if anyone else is thinking of buying this bar beware of this fact that i only came to realize after i have purchased the bar. i still plan to use this bar even if i have to purchase the hotchkis control arms set, but i am hoping to still make my factory arms work since i have already boxed them and installed eurythane bushings throughout. does anyone have the hotchkis control arms set on their car that would be willing to tell me where exactly i need to drill the holes in my control arms so that i may use my new sway bar?

I have that setup on my '66 and can take some pictures tomorrow and get some measurements for you.

I tried to tape a small tape measure along the control arm, but it was so dark the flash washed out the measurements. Measured from the center of the rear mounting bolt hole, the center of the sway bar holes are 4.5 inches and 10.5 inches.
