Convert Proform ignition to Pertronix?

In the 80's I worked for a large parts store in town and a guy had a Jensen. I THINK it had an RB in it One day he came in with this magnificent wood dash, but damaged. He brought in in to show me and some other guys. It was walnut/ mahogany, don't know, but very high quality. He said he'd ordered one from England, I don't remember how long it took, but he claimed it wasn't very long at all. I think the earlier cars came with early hemis. I vaguely remember one parked at the National City (San Diego) Plymouth dealer and it had an early hemi in it
