looking for correct bumper jack base

Hi Y'all,

I am looking for the correct bumper jack base for my.67 cuda. I bought a correct bumper jack from another member here, he included 2 bases, but neither one seat into the jack. I got a good deal on this part but still need the correct base for it, as well as a tire iron for the larger lug nuts used with the bigger bolt pattern setup.

Anybody got these parts and would like to part with them. I am interested.

Matt
