HURST Shifter Rubber handle isolators and retaining clips

[CamarosRus]

Looking for lower cost alternative supplier of the Rubber Shifter Handle
Isolators and the Stainless Steel Retaining Clips

And do they have to be purchased in sets or can I just buy the
stainless clips separately

I was quoted $33 for the 4 pcs (2 clips / 2 rubbers)

Also need the rubber bushings that go into the three levers on
bottom of 3138 Hurst Shifter
