What pro chamber to get?

I just dropped 351 svo motor in my 95 gt.I got a set of 351 swap shorties for 87-93 so I wouldnt have the egr tube to plug.I was needing some help on rather I should run a 87-93 prochamber for shorties or a 94-95 prochamber for shorties.If anyone know the difference in the two or has so ideas please help,Thanks

I originally bought 87-93 1 3/4 swap long tubes,but the guy did not have them in stock.I could not find longtubes for are year.so anyways he offered me a set of 1 3/4 inch ceramic coated shorties for same price,wictch was 100 under list so I got them.I have been told the only differance in the headers for are year and fox is the egr tube on ares, which I have blocked off any ways on my old motor.Bye the way you car is almost identical on mods as mine.Only differance is I will be running a D-1 procharger instead of p1,plus mine is black.
