As long as they are the right size injectors just get new orings and grommets and pop them in there.

That 57 trim isn't one of those ebay specials is it? If it is you should look them up and read about their self machining compressor wheels.

The regular ford type 1680cc injectors dont fit in the stock fuel rails. You will have to either take a drill press and drill out your stock rails to fit the 1680s, shim the 1680s down to fit in the stock rail, or buy aftermarket fuel rails. On Injector.com they do sell 1600cc injectors that fit in the stock rails though, You just need japanese style injectors.
