Juki LU563 takeup arm replacement

[TheMortgageGuy]

Hello group experts. 
 

I moved in July and the movers broke the take up arm on my Juki Lu563. I had a local company repair the machine paid for by the moving company. $730 repair cost. I got the machine back and it doesn’t seem to be sewing properly. 
hook is too close to the needle, hitting it going forward and appears to be slightly off going in reverse  . I spent hours in the past getting this machine to perform flawlessly using help from this forum. Unfortunately the arm that was installed appears to be shorter and does not have the same lift and extension as the original arm did  

attached is a pic of the new arm installed on the machine  

 

I am sure that the old arm at least extended to the front edge of the flange guard to the left of the arm and the new arm does not extend out that far  

 

kind of like a Juki lu562 arm and upgrading to a 563 arm when doing a big bobbin conversion 

 

am I right ?  Is this the wrong  arm? 
thank you
