OK, so I thought I had a sure grip for my 8 3/4 742 center, I pulled the 489 4:10 cuz I sold it and just for the heck of it tried to insert the axle from my b-body rearend in to the sure grip that I will be installing and it appeared the diameter of the axle was, lets say 1/8" larger than the sure grip opening. :wack:What sure grip might I have? Batteries were dead on my camera and forgot my phone when I went to my shop so no pic's.
Sure Grip units, and axle diameters?? Help??

Count the number of splines on your axle, and compare the count to the number of splines on the carrier. Are the axles stock? I've heard some say that Mark Williams axles use a slightly different cut on the splines than other manufacturers.
Is it a clutch-type Powr Lok sure grip? It could be from a Dana 60, with a different spline count.

They are the stock b body axles. The sure lok has 2 springs close to the opening if that helps.

Sounds like the Borg Warner unit. I'd be counting splines, if it were me.

That style of sure grip was used in tons of stuff. Without more information, it's hard to know what you've got.

Betting it's an 8.25" carrier, not an 8.75".
Whats it worth if it's 8 1/4

Try using toothpicks to count the spline count. You just need two. 1 one to mark where you start and the other to use to count the rest. I use this method when I'm super wore out but need to get the job done.

There are 27 spline 8.25" carriers. A stock 8.75" should be 30 splines.

I think a 27 spline shaft will be 29.5 mm (1.16") and a 30 spline shaft will be 33.3mm (1.31").
Looks like someone sold me something they knew nothing about. I buy stuff and put it on the shelf til I need it without verifying that I got what I wanted. It was suppose to be an 8 3/4 unit. I need to start checking it when I buy it. I bought this last year. Anyone need one. It is now for sale for whatever a fair price is.
..........interested in a trade..............tell me what u need.......kim.......
