Title: gear/axle questions???
Post by: BIG CHEVY on October 07, 2011, 03:49:53 pm

i got a 79---350--350--203.    10 bolt front....12 bolt rear.   308 gears. i want 373 gears.

now the questions....

are these 8.875 gears?
when u go to randys r&p it has dif gears for truck and car? what is different?
if i got 3/4 ton axles do i need dif gears?

i know a couple people with some sets....i need to be educated to be able to negotiate. wouldnt want to buy the wrong things.

     You are right, there is different size differential sets on our axles for our trucks.  Your set should be 8.5 though, front and back.
