2v = different intake bracket/rod/lever
4v = intake bracket is taller/rod is longer/ lever can be long or short depending in VB.
yes, go get all of it from carb slide rod/brar/intake bracket/1 piece down rod/ptk lever
if you are going to use the stock intake grab the q-jet that's on it as well.
this is the best way to convert over to 4v on the trucks.
q-jet to the ptk lever
should have a q-jet duel snorkel air breather on it also
may have the 360 center dump mannys with the long tube y-pipe with no cats or 1 cat mid stream after y-pipe. the long y-pipe is great for chopping into duels.
