1964 Dart Rear End

[SOCAL64DART]

Have a stock Dart and im trying to find out what kind of rear end it is.
It has a 225 /6 in it.
Can any of you tell me what Size Rear End it would have?

Most likely it has a 7 & 1/4 and could have 2.76, 2.93, 3.23 or possibly 3.55 gears. My slant 6/904 Dart GT originally had 2.93's in it. My slant 6/3 on the tree Valiant has 3.23's in it.

if its all stock its a 7-1/4.

 

[Orv Grote]

If it has nine bolts on the cover it is a 7 1/4". 10 bolts it's a 8 1/4.
No bolts it's a 8 3/4" (highly unlikely for the last two).
