Yea do it if you want, they're an appearance mod just like alot of things. More appearance than function. Either way I really like your car
I'd say leave the 4.10's with the T56. The difference in first gear of the T56 to your 5spd is going to be a big enough difference. Plus with that long 6th gear, cruising on the highway with 4.10's wont be a problem
Keep us posted!
