OK, I found the Mopar extension for the trucks with a bent tube.

Part # 4173223 There is a NOS one on ebay for $69.99 right now. At this time, I'm going to have to hold off for a month or so (I blew this months truck budget already). It appears the person that has the NOS one listed puts one up for sale about every few months, maybe when I can buy one, he will still have one listed. I guess what I'm saying is if you need it, go for it.

HP383, the one on Amazon is the same one Summit lists. Both places say it does not fit on my 96 Dakota 5.2 motor. Also, the reviews say there is only one tube in the package, not the two tubes shown in the pictures. One of the tubes is the one I would want, the other is the press in one, and its pretty unclear which one you get. Unless someone has actually purchased one and knows you get the 1/4 turn lock one and it fits in Mopar valve cover, I'm going to take their word it won't fit.
