I have a jig that I used to hold my haldex diff in place on the syncro beam while I made a conversion bracket to hold it permenantly.
Even if you buy the dutchdubs conversion kit you still need a jig to hold the haldex diff in place of the syncro one.
I can get photos, PM me.
£50 delivered.
Using this, and £12 of mild steel I made my own cage for the haldex diff and happy to give the buyer of this, any pointers and help.
