i once had a v6 cossie sierra i built,i wanted to use a cossie arb,so i had to use cossie track control arms,the pin that goes through the hub on a normal sierra is totally different,so i used xr4x4 hubs with the cv joint from a 4x4,i just removed the driveshaft.it worked well,maybe if you are determined to use the leda gear you could do this!cheers,lee
