DJPEPE AND OTHERS
I can attest to the quality of Alexanders detent plate, as I installed one in my 58 last winter. It not only provides a solid secure position, for you shift lever but it is better than the original.In some cases as mentioned on this site " see detent plate" in search field older cars with worn detent plates had serious movement once someone shut the doors in a running vehicle due to the plate being rounded and worn.
I strongly recommend all older birds, order them and get them installed.
