I'm looking to upgrade the diff and axles on my 2 zeds that now run stroker engines. Both of these have very clunky drivetrains that I feel wont last much longer when I start to abuse them. So I'm looking at CV axle conversions to go with 2 of the diffs I currently have. These include: R200 plate 3.9, R180 STI helical 3.54, R180 quaif 3.34, R160 suretrack, plus sever open R200's. So I'm looking for options that include direct fit to R180/160 STI diffs and and standard datsun flanges. I do have STI to datsun custom flanges too. I recently looked a a US company selling shafts in either direct STI fit or datsun flange but cant seam to find them now. I'm sure the webite started with datsun and these shafts were under $1000. Any help much appriciated.
