Part number ATP Y-924
Its $18 on amazon. My speedo bounces at lower speeds but steadies out after i think about 20 mph.
My concern is to my understanding an auto MJ without cruise control needs a much much longer cable, that one lists as 12"...although I just read reviews on Amazon for it and a couple guys said it worked on their non cruise..I think I may give it a try! O rly....
The Y-924 one worked for me it was i think 36" the Y-802 one was something like 14" i grabbed it because it matched corresponding part number i found, but the length wasnt right. I read up on the Y-924 one and decided to try it, worked for me. I have an 88 without cruise control.
