They should have all been made that way, but then they would not be special.
That cleaned up nicely good job, Did my 520 a couple years ago. Did you upgrade to LEDs yet?
I did on my other 521 but forgot that I hadn't so when I get some extra cash I'll put some in. On a side note the 9 led cool white for my dome light has been discontinued.https://www.superbri...rofit-car/9/67/
I bought a 411 sss cluster that was pretty rough. It cleaned up better than I thought it would. Good enough to use the face from it. The speedo was seized and the rear housing had some extra brackets so instead of cutting them off I just swapped the gauge face into my cluster.
Getting the top screws started ended up being a nightmare. I got one but trying to get them in straight without little kid hands was worse than getting the carb nuts off a smogged 210. I ended up re tapping all four holes as they were super tight.
