61 C10 Suspension Upgrade Question.

[ravidmnas1]

I have a 1961 C10 Apache, I want to upgrade the front suspension, but here is the deal. I have a 1976 Frame that i want to use instead of the old x frame, and a company called Total Cost Involved makes a whole kit but lists its only for a 1963-1972 c10 and was wondering if could be retro fitted to fit a 1976 frame? What all would need to be done. I tried contacting them with no luck to my question. Thanks.

Here is the kit in question http://www.totalcostinvolved.com/p/1...-plain-package
