I just installed a 96 Explorer U/L....This yr had the internal EGR passage, thats why i got the 96....Just in case i want the EGR, its there...Other years were external on the EGR...
Good luck. most salvage yards now their worth, and they sell quick...the GT40 heads on the same motor can be harder to find...depends where you live i guess...up here in N.E., they can be hard to score thru a salvage yard...they usually have guys waiting for em....people are asking some decent prices for em..you gotta find that smokin deal, ya know...
For what its worth....since i scan classifieds alot...you can score a GT40 lower for right around 100.00 and the Cobra/94-95 Cobra uppers/GT40 tubular uppers can be had for around the same price....Explorer U/Ls are going for like 200-250, and then add the shipping in??? So shop around....a GT40 lower, even off and Explorer will take all the above uppers....seems theres more and more for sale lately....
some dude last week on Corral, was selling a 94/94 Cobra upper last week for like 100.00...
Scam at GT40 lower for cheap money and your done....The Explorer upper needs an elbow, so theres a few bucks too....
Tmoss in the 5.0 tech side has some info on Ex years and such...you could PM him for the skinny....
