Feral does a conversion on these for your "A" series engine, & the Bosch distributor that you have was used only on the 83/84, series 2 Bluebird, in Australia
I provided him with a few "core" distributors when i asked him to make one for me, so drop him a line & he may be able to do one on an exchange basis.
Make sure that you tell him which cylinder block type it is for [A10/ 1200 type, or the later A12/ A14/ A15 type] Check this
website, page, then send him an e-mail.
I expect to pick up my distributor during next week, so i will post a picture.
To get the best from it, you will need to use the matching high energy type coil. That will really make those plugs throw a spark
