170v.de - das neue Forum

hello
I am a new member of the forum and I extend a greeting to everyone
I have started restoring a pre-war 170V and have some problems
the first problem is that on my car there is no steel structure that supports the front seats.
so I will have to rebuild it but I am not in possession of the measurements of the various elements.
hope i can get some help from you
Thank you

hier meine Vermessung der Sitzschienen Bleche

Thanks for the info
with these data I will be able to reconstruct the structure
best regards
Antonio
