I am in the process of gathering parts to rebuild my 742 case. I have 4:10 gears and the install kit. What should I get for the carrier? Locker, suregrip, suretrac, etc...

It's a summer car that will be at the dragway 6-12 times a summer with slicks.
I currently run 12.4 @ 110 in the 1/4 with my 3:55 gears.

Suregrip works for me.
Cass sells them new. Most older units have internal gear wear and excessive runout after 50 years of use.
Mopar 8 3/4" (8.75) Clutch Type Sure-Grip ("Powr-lok")
 
The Dana Power Lock is by far the strongest clutch type unit. The Torsion unit is nice in that it has no parts to wear out like clutches. The Detroit Locker is an almost indestructible piece, but it does make noise on operation.
 
The 742 case I have is an open diff.

Thank you for the replies.
 
So I ended up going with a sure grip from doctor diff. He just got them back in stock. I Ordered it last night .

Thank you for all the replies
 
So! Which one preferred for serious street power?
