If it won't work, you might consider just converting your point distributor to a pointless conversion kit...Pertronix makes them and it just fits into your existing stock distributor.
Crane makes a pointless conversion kit that has a rev limiter built in, I was it on either Jeggs or Summits website. I also read on a Camaro forum some Chevy guru using these kits and changing out the coils to high output coils...for about $100, that way the existing housing is OEM and the advance curves stay the same...you just get rid of the points. MSD, Accel, Petronix and the other major manufactures make these.
I posted a question to the other Pantera forum and four people said they had used this type of conversion and they work great and no failure for 8-10 years so far.
