Against all the advice on this forum, I decided to retain the original 7 1/4 rear axle in my 65 Dart. I want to keep the stock small bolt pattern for use with the Cragar wheels I've already purchased and to match the Kelsey Hayes front disk brakes that I've also already purchased. That rules out the 8 1/4 option. And I'm not wild about the expense and additional unsprung weight of an 8 3/4.
It's going behind a 273/904 combo with factory four barrel, Egge domed pistons and an Isky E4 cam. Compression ratio should be less than 9.5:1 and I'm not one to abuse a vehicle.
I have read that the sure grip versions hold up better due to less wheel spin and also due to the presence of 4 spider gears instead of 2.
Based on all of this, I purchased a 7 1/4 sure grip differential from FABO member Freezerman. He removed it from the housing for me to cut down on shipping weight and it arrived quickly.
I gave it a bath in gasoline and took it apart to see what I had. Turns out it's a cone style sure grip so only 2 spider gears.
Does anybody know if a later cone style sure grip will fit in my 65 axle housing? I guess there is one way to find out.
Here's some pics of the sure grip. Cute, isn't it?
