Ok, first what years did they make the Big10? Second, I can get a complete Big 10 front end for free, cross member and all. i was wanting to install this onto my 1969. Now I looked at the books at work, and I don't see seprate part # for big 10 front end parts, brakes, suspension, springs, ect. So I guess what I'm asking is, is there any diffrence in a Big10 front end, as to opposed to a regular C10? I am worried about bolting this thing to my 69 and making it sit goofy. And in the future, I wanna get droped spindles for the front.....later down the road. I'm gonna be swapping the engine this winter in it, and I suppose this would be a great time to swap the front cross member out. Thanks for any help, Jason.
