I see that the only place to buy any 80% lower router jugs are on the modulus website. Oddly enough modulus no longer sells their model but now sells 5d and 80% jigs.
I am trying try find a replacement top plate.
Is the 80% arms Gen 3 top plate interchangeable with the 5d?
Some of those jigs use the same design, but might use different threads or mounting screws.
