Well I did it, I rebuilt the bendix carb on my 1974 JDX4 special. I looked as others have and did not find anything. What did I do...I did what any other bendix carb person does,cried.
After that, I sat down at my CAD system, drew them up and had a set of gaskets cut out by waterjet!
Fit like a glove!!
If there is enough interest I will have a few made (gaskets sets only, with viton o-rings and upgraded gasket material...can't help with the needle and seats) for a reasonable fee.
Please email me at strmbrg89@q.com and let me know if this interests you.
Thanks, Robin
