I have a 7.3 I/C installed in my '95. I bought my intercooler off Ebay, and had Geoff at GTSmotorsports install it for me.
He has a "kit" which makes the job much easier, so you could contact him if you'd like.
You can see his kit on his website
GTS Motorsports where you then click on "Ford Peformance" and then "Intercoolers" on the next page. You can see what is available with his kit on the "Intercooler" page.
