What rear gears?

How can I tell what rear gears came with my 66 Dart GT? It's an auto. Is there a fender tag code, or do I have to open the pumpkin to find out?

No, you don't have open it up to find out...open the link and scroll down where it says "whats my ratio"

oops! Gotcha... Seems easy enough.

Thanks again!

Mine originally has 2.76:1 ratio in a 7 1/4" rear with the small bolt pattern and 13" donuts for tires. :sad2: If you look at the rear end center section, the original gear ratio tag may still be attached to one of the cover bolts.

Sid-

That's what I'm expecting, too. I have the 13" donuts!! :)

My ole 65 273/auto had 2:76's also....My rear thats under my 66 wagon came outta a 66 cuda wit slant 6/auto, and it is a 2:76!!....REX

Mine came new with 3.55/ 8 3/4 but it is a 4 sp. and 13 in tires. I had them worn out befoe i got 10m miles on it.

Ehhh, open the cover up or pumpkin out and change that oil!

LOL!
