Is the Birkin cowl dimensionally the same as Caterham?

Hey, Folks.  Last Friday a guy (insured) hit the back of my Birkin 7 in the fuel filler area , Shoving it sideways & denting / tearing the aluminum.  Rear skin is ruined + the RR wheel arch is now nearly touching the back of tire.   Yeah, it's a bummer.    I got an estimate from a shop (I have Hagerty) but the shop is not, specifically, a Lotus or Aluminum Fabrication kind of place.  But they do some great hotrod / vintage / custom work. 

 

   My question is:  Do you think that a highly-skilled , but not Seven-Knowledgeable regular body shop to do this kind of repair? It will need a new rear skin fabbed & installed.  Maybe even some rear frame work. 

 

Thanks in advance.  Perry.
