I'm gonna do a gear swap soon and was thinking of goin with 4.10's over 3.73's so what's ya'll input.Also how can you get you're speedo to read correct after a 4.10 gear swap?My car is a 91 auto with 275/40/17 on 17x9 rims.I know you can swap out the little plastic gear inside the tranny but I've been searching and I only see ones that correct for 3.73's I'm sure they have to make one but I must be missing it.Also does anyone see any adverse affects of running 4.10's because my understanding is the aod doesn't have the output shaft bearing problem like the 4r70 and yes I know my gas mileage will drop but this isn't my daily driver I just figure these heavy cars could use all the gear I can throw at it to get it rollin.So am I missing anything?All input and opions will be appreciated.
Thanks Jay
