7.25 open rearend >> to suregrip posi. HOW TO.

Yes . that is what I read up here on the site.. not to many people like these 7.25's .. the suregrips are stronger though....My brother an I had a bunch of dart and cudas over the years and never gernaded a 7.25 .........even behind a 340 .Guess we got lucky then. I think you just have to be conscious where and what kind of surface your opening it up on ... ... if it's a rough road, hit a pot hole .. or do a burnout over the RR tracks then you will break it for sure... WE even took a few of those cars the track and race then down the 1/4 mile.. always drove them back home 50 miles away.
Since I have both of these rear ends just thought I could build a nice 293 posi . without to much trouble and $$.
