Well i have finished installing the alloy arms but when i did mine i also had to conert my swing axle to i.r.s. the set up is complete bar the axles which i still have to sort out. using a 1303s box with 181 out put flanges and hope fully going to use 944 axles if they are long enough, if not will have to try the longer t2 shafts as these will mate up with the drive flanges.
