wrong part #?

Have a 66skylark gs conv. Ordered the Idle arm, a moog k-5142 rock auto says thats the part number as well. But its not,will not fit on the frame anyone know the real part number?

 

Everything I find shows that k-5142 is the right # for 66 GS. K-5143 is also listed for 66 Skylark. o No:

See here: http://www.jegs.com/i/Moog/719/K5143/10002/-1?parentProductId=764026

 

Looks like the 5143 is for 68 and up. Bolt it to the frame and rotate it. It should work.

I measured five 67 centerlinks. One from each car: Skylark, rag Skylark, hrdtp Special, GS400 rag and a GS400 hrdtp. They all have the 7/8's bar. If you have the 7/8's bar the k5142 should work. If the bolt hole spacing is different perhaps you have the wrong part in the box. It's happened to me when I bought a moog tie-rod.

According to this applications list from Egge Machine Co. some 64-67 with a 13/16"s centerlink would use the 68-72 K5143 idler arm..........Ray
