1967 front suspension

[kanuck]

I know I've ask part of this before and was told I could bolt in a cross member from a 73-82 to get my 5 lug and disc brakes, but I was just wondering if I plan to lower the truck a bit if there is a spindle availible that fits on my control arms that is both a drop spindle and converts to 5 lug disc, would this be a cheaper and easier way to go. Also the truck is a 1/2 ton yet sits fairly high, could someone have put in heavier springs, or did some of the factory ones sit high??
Thanks Hagen
