This linkage is a simple solution to a sometimes over complicated problem. We use 73-76 shift linkage ends as the core ends with new bushings and a new straight section for the linkage. We have used these on over 25 conversions over the last 6 years with great results and even use it on our personal car.
A core charge will be assessed of $75 if you do not provide the core ends.
I have several seconds that I am offering no core and at an 80 dollar discount
