There`s a couple other members here with the Core shifters. One of my absolute favourite mods.
They use an actual Hurst shifter arm. Core makes the tower. Exact duplicate of the original Hurst part that they no longer make. It has less play in neutral than the original had when it was in 1st. The few (very few!) people that have driven the truck other than me, have all come back with rave reviews! Guys at the body shop all had to take it around the block once, just to play with the shifter! It`d be even more fun with a 5.3 in front of it!
Never knew one was available for the NV4500.
