Re: 1996 major differences are there any?

If your mind is made up, ok, but that is the best fuel injection ever put on the 300/4.9. Mass air, so you can finally drop a cam in without the hassles. I have a warmed over 96, and love it, best power and fuel mileage I've ever gotten from a Ford 6.

Re: Lost my screws for my carb

You will probably have to buy a carb for parts at a junkyard. There were millions of them sold, so there should be a few around there were a lot of other applications. The only bummer is junkyard minimum, even if you have $.05 worth of stuff it always seems to cost $25 or more.
