Thank you for the photos.
I would suggest that you either
1. Purchase a new 948cc clutch pressure plate, driven plate and carbon thrust and trust it will all work.
or
2. Upgrade the clutch by fitting a 1098cc rear engine plate, flywheel, pressure plate, driven plate, carbon thrust and clutch release fork/arm Pt No: 22G166. The gearbox front cover for a 1098cc gearbox should be Pt No: 22G118. The part number is cast into the front cover. Check that you have the correct front cover.
You have the wrong clutch release fork/arm currently fitted!!! If you look at the photos you will see that the carbon thrust is off centre relative to the first motion shaft. When I did the 948cc clutch with 1098cc gearbox conversion way back I had to relieve the inside top of the carbon thrust to allow the carbon thrust to press on the clutch cover without fouling the first motion shaft. It does look as if there has been some fouling between the two.
Whilst the standard 948cc release arm has a bend in it the arm shown has a pronounced bend and it may have been heated and bent to suit. I had to heat and bend the release arm on my conversion to get the right leverage/clearance.
Here are a couple of 1098cc rear engine plate for sale on 'e' bay

My preference would be to upgrade to all 1098cc parts which will make life much easier as you will not have a miss mash of parts and you will know that it will work as it should.
