Hey! You're the best! Thanks for the reply. My main interest in the 78 is the somewhat new 350 crate motor in it, and the "built turbo 400 trans" that is in it. Since my truck has a straight 6, I was wondering if the 78 dif might be needed too... if I go with the V8. Maybe my existing rear axle will work with a gear change? Not sure what I would need for a driveshaft either. Also wondered if I can easily use the automatic pedals in my now 3-speed truck when I use the Turbo 400.... and maybe even the steering column with the column shifter... Seems like the 78 offers a lot.. but I need to know the parts can be easily adapted to my 65. One more question is.... do you think my wife will kill me if I bring home another non-running truck?
