What to use for ignition high HP engine???

[STREETRACE69]

I got the old box back and I am going to pop it open to see what the deal is. It has the exact dimensions of a newer box. There was an article in Hot Rod when they were building the retro blown 67-8 Camaro and they make a note how they sent in their vintage box to have it updated?

When I 1st called they said they could fix anything or update. When I sent in that all changed and the supposed part that went is obsolete and there is something in the newer that won't fit?

I will post pics before and after when cracked open. I jokingly asked if they would honor the warranty card that came with it.
