Upper control arm bolt size

[spabula]

does anyone know what size the heads of the UCA bolts and nuts are?? I don't have my tools where I'm at and was just gonna pick up those wrenches/sockets for the job. I looked through all the other UCA posts and didnt see them anywhere.

I forgot... it's for a 2000 Ex AWD

i used 21mm for the bolts on the frame and 15mm for the pinch bolt on the spindle.
