If you have an original Ford script bad condenser, you can carefully open it up and replace the insides with a modern part. I did a couple just to see how hard it would be to do it and to see how well it woould work. I'm still using one of these in the picture, which I cut apart and changed 3 years ago.
It's tough to unroll the crimped end, so the second one I did I used a tubing cutter and soldered the seam.
