Can you help? 1924 Renault Model NO spring mounting

Hello,

 

I have a question. I own a 1924 Renault Model NO and am trying to establish the correct location on the chassis of the cast spring hanger for the rear end of the front spring. In particular, the centre-to-centre distance between the fixed hanger bolt and the front chassis spring mounting point would be extremely helpful.

 

I feel confident that this information must be out there somewhere, but I have been unable to find it so far. Can anyone please help?

 

There may well be others with similar questions who are also finding it difficult to obtain the information they need. Any suggestions would be greatly appreciated.

Best regards to all the team,

Christopher Musk
