Hello .I am having difficulty in getting my new speedometer cable adapter to work. I have a Buick 29-41 .I recently purchased a good used speedometer cable assembly. On this cable assembly ,it still had the die cast adapter pn 848188.It has swollen and is too large to go into my transmission.so I then purchased from CA ,a new brass adapter .It fits beautifully into my transmission.It has cast into it pn 848188 as well.The problem is, the bore that the outer cable housing goes into, on the diecast part is approximately 2.2 inches deep. The bore depth on the brass part is approximately .9 inches deep. I know that it can be drilled or bored to match the depth of the diecast part,but Id rather not.Has anyone else encountered this problem? I hope that Im using the correct parts.I have no original part number resources.Thanks
