so i bought a 4.7 tcase for what i now know goes to a w56 tranny but the rails were too short for my g54 causing it to not shift into 4low so i called up marlin and ordererd an extra set of the correct ones to install but my question is will i be able to swap just the high, neutral, low rail or will i have to swap the 2w/4w as well because id really like to avoid splitting my case if i dont have to thanks!
