I try to explain what Verena has already stated in earlier email.
— The part what your customer has asked for does not exist:with this dimensions: (citation: "Customer inquiry is : Ringspann FXN 61-19/95 DX, Bore dia = 34 mm. ,L = 35")
There is no FXN 61-19 with L=35mm existing, please see our catalogue 84 for reference.
— The only freewheel with the dimensions you sent is the FX 61-19 DX special but this is NOT available with outer ring. This freewheel was designed for a customer who manufactures the outer ring himself.
This is the reason why we have no outer ring for this special freewheel.
— The only thing we can do for you is to offer the outer ring of the standard freewheel from cat.84 as separate part. But this has the width 26mm and NOT 35mm !!!
We can not know if this part fits to the application of your customer or not. This is on your own risk.
