I'm sure it will make it easier. I use a small flat head screwdriver to wedge the tab away from the groove, and then work the arm off. PITA! Requires three hands. lolYeah I have the same wiper issue too. I just don’t feel like fixing it since I’m not driving the RC in the rain anymore. Apparently there’s a wiper removal tool you can get which makes it a lot easier for our trucks. Seen an old timer on YouTube do it in a few minutes.
OK, thanks. I see that arm still has the spring clip on it, so the tool must apply enough force to override the spring tension. Cool!This is the video I seen with the tool.
I’m unfamiliar of the 70s set ups unfortunately but it looks like it just uses leverage as long as you can hook it.
