I have a 1981 BJ44 with the compound wiper arm and have two questions. My spring is no longer creating tension against the windshield so I bought a set of replacement springs for the FJ40 and they are too long to create the correct tension. Also, I have never been able to find wiper blades to fit the arms.

Question 1) if anyone has one of these compound arms, could you send me a picture of the spring on the underside that pulls the wiper blade into the windshield? I never had an oem one and want to see how it is shaped and how it sits in the wiper...

Question 2) What is the width of the wiper arm on normal 40s here in the states? Every time i have tried to fit a US wiper it seems too narrow. My arm is 7mm wide and the raised retention thingy is 17 to 18mm from the end. Anyone have this issue before?
