I have. It's not that big a deal. It makes fitting extractors a pain though. I just had to weld a couple of plates to the origional mounting brackets. There is another way, I was going to do it a bit neater by removing the old 1200 crossmember mounts and welding them to the 120Y crossmember the same way I did my L series 120Y crossmember. That is the way I would do it. Looks neater by far and will be less hassle if John Q looks under the bonnet.
