will 4th gen gears fit on a 3rd gen.
I'm talking about 3.23s out of a 2000 SS onto a 88 IROC with 2.73 currently?
well?
thanks guys

I can get them real cheap, if they fit......

 

yep they'll fit, only concern is the carreir series you have, long as you have a 10 bolt and not 9 bolt or the dana 44

 

If your car has 2.73s, you'll absolutely have to get a carrier. No way to put stock 3-series gears on a 2-series carrier.

Don't forget, your rear is 26-spline; you'll either have to get a 26-spline carrier, or get 28-spline axles to use a 28-spline carrier.

All of this assuming you have a 10-bolt of course.

 

ok, in english?
how much more would I have to spend in parts to make it fit?
if I had 10 bolt....
how do I tell besides climbing under the car and going 1..2...3...4....
thanks

BTW I know nothing of much anything anyway.....

 

actually if it's the iroc in your sig you most likely have a 9 bolt, easy check is a rubber plug in the rear cover as well as the 9 bolts, and if it's a 9 bolt 4th gen gear sets won't work, but the entire rear isa direct bolt in, except for the back spacing differances on the wheels.

 

thanks
car started out as a 305, but Yea I think I remember a rubber plug back there.
guess it's a whole new rear I have to go for then.....
