For sure adus 505 fits the UCF20 chassis. I have those installed and mine is a 95.
The 583 kit comes with with 2 bushings. One for the bushing on the spindle/hub side and one that goes in the lateral arm. It is confirmed that the bushings on the spindle side fits but not the actual arm side. Here is the thread for reference:

Im trying to compile a list of compatible bushings between the ucf10 and ucf20 chassis. So, thanks to you, its now confirmed that the Adus 578 fits both chassis eventhough only labeled for the 1st gens. Have you replaced any other bushings on your 95? Im also trying to confirm whether the front lower control arm bushings fit both as well.
