I'm sorry to hear that. He has been selling on eBay since September and has a 100% feedback so I wouldn't have expected it to turn out negatively for you, hopefully things will still work out.
It sounds like your getting a pretty good deal on the console and gas pedal, I'm just wondering why you want the K-frame and rearend. If you already have a K-frame in your car, they are the same whether it is from a /6 or V-8 car so you shouldn't need another. The 7 1/4 rearend isn't really worth anything unless you just need a rearend to move a vehicle around your yard. I wouldn't trust one if you are planning on putting any kind of horsepower to it, that's just my opinion though.
I'm sure you'll find others here that want to disagree with me and talk about how great their 7 1/4 or 8 1/4 is, but it sort of reminds me of a local friend of mine that likes to talk about strong running /6's. Yes there may be some out there, yes theirs may hold up to their motors, but let me put a 500 ci motor, 4-speed, and slicks to it. It's a gernade with the pin pulled waiting to blow. If you've got the money then why underbuild so you can upgrade later, when instead you can build it right the first time and never touch it again? Just my $.02, sorry for the rant.
I'll keep an eye out around here for somebody parting one out, or if I end up buying one this summer to part out I'll keep you in mind.
