If you wanted a quicker box for more sporty type steering, you could use one from certain gm intermediates from the 80's era with option code F41, MonteCarlo SS, T-Type/GN, 442/Salon/calais, GP 2+2 to name a few, these models will have a faster ratio box, where as there common base models have the identical box to our eagles, lol (even same part #). There is always the f body box that's suppose to fit into the gm intermediate which is said to be the same as the F41 box, but I'm unsure of the year range on that.
