Can someone show me the difference between vette and f-body fuel rails, valve covers?

I am having a hell of a time. Al pointed out I needed the f-body valve covers to put this motor (98, from a vette) in my 99 Z28. I can't seem to find any for sale out there that look any different.

Also, I know the fuel rail on the vette doesn't have a return line and has a built in regulator. All this I have found out reading various things online. I need the right rail, but how can I tell the difference. Every one I look at, regardless of the vehicle, seems to have no return line provision. What am I missing here? they are all over ebay, I bought one from a guy on ls1tech, etc. Just can't seem to find what I need.

Help a brotha out ;)

Mike the valve covers and fuel rails are the same, but looking at the pic it appears that you have 2 passenger side valve covers on your engine. I have some 99+ covers you can have, but since it appears your engine is a 97-98 you need the perimiter bolt. Your fuel rail has a dual feed, whereas the 99+ C5 and F body are single feed lines.

I dunno, seems like every pair of perimeter covers I see for sale on ebay has the same two filler necks, but they have all been vette covers

This might help
