I tried it again last night.
The issue that I having the alternator swinging downwards (XR2 bracket) is that the alternator adjuster mounting hole seems to be 180 deg round where it should be, thus hits the X-member when I tighten the belt.
Included in that issue is that the only way for me to put the adjuster on is with a series of brackets, to reach round 180 deg to mount onto the alternator.
Any pics of the alternators mounted up would be brilliant!!!!
