The previous owner of my car fitted a newly-fabricated English axle at quite great expense. Sadly it was pretty hopeless. There was no brace and a split A-Frame mount meant it leaked oil in quite a big way. Furthermore, failure to remove the old bumpstops didn't help handling. (Oh, and oil used to centrifuge into the nearside wheel due to bearing issues). Thankfully James Whiting was able to put together a properly engineered replacement which (touch wood) has been completely trouble free.
