I need to install an adjustable prop valve in the rear to keep it from locking up on hard stops.i have a 14 bolt with discs in the rear.ive done this before on other vehicles but ive always installed them in the rear by the diff.the problem ive encountered is that they got cruded up with mud and everything else and basically became unadjustable in short time.i would like to keep it under the hood in the eng compartment but how would I route it to get it up there?it still has to go thru the stock prop valve too right?
