I have doubts about the advance unit ,,,the plate,,maybe. I will compare bits between my shovel head and my Bullet.
I believe the HD condenser would be an issue. Although the voltage is the same between the two applications the coils are quite different. The HD of thoes years used a coil with a "double wound" secondary. The 'tuned' value of the condenser would most likely be slightly difference if max. available voltage were expected from the stock RE coil. By the way, what is wrong with the stock RE set-up?
Done this allready, but simply made my own plate and fitted Bosch v-dub -mercedes points instead. The chevy 6 points were my first choice were not suited (too large). What is wrong with the the stock points? Availability, and the 2 piece design is a nightmare on the side of the road. Now it's just one spade connector and one screw.There is a pic of this in modifications . I did not try this but, you might be able to just drill and tap the original plate for the bosch points, there may be room.
I use the bosch condenser, 2+ years now, stock Lucas coil, no problems. Like I said in the above post, it was only after I made the new points plate that I noticed that I probably could have just drilled 2 new holes (one tapped) in the existing plate. It really is that easy.
