A-arms for c20

[ncC20]

Hi im in the process of converting my c20 8 lug to a 5 lug. I've got new spindles from ECE new rotors upper and lower ball joints inner and outer tie rods calipers and hoses. Once i started putting it all together i noticed the shafts that run through my upper a-arms is completly stripped out not only is the shaft stripped but the threads are gone out of the a-arms. So my ? is where can i get a tubular set of a-arms for my C-20
