Man am I late on this thread, just found it today, wish I would have known I would have set up a time where we could have met each other when you came to Hamilton, that's where I am and "Two Scoop's" my 73Dart Swinger. Now if I can get this to work I'll show you what the 318 that's going into Two Scoop's used to be in. This was my Brother in-law's Arrow this is what you could do with the 79 you found.
