I am cleaning up a 65/6 width 9 inch rear and I have. It has a 3.5 trak lok and 31 spline axles. It is complete over kill for what I am installing it in which is a 67 fastback that will never have a big horsepower setup but I like the higher numerical gear ratio for pep and I like the narrower housing because it makes it easier to put the wider tires on that I like to run.
I am taking out the 67/8 width 8 inch rear out of my 67 mustang. It has 28 spline, 2.79 gearing.
I would ideally LOVE to have a 65/6 width rear with the tapered tubes....because that will get me a small bump in rear height.
So if anyone has either a 8 or 9 inch 65/6 width rear with tapered tubes (most likely 8 inch since the 9s are rare) with a 3.25 to 3.5 ratio that want's to work out a trade......for either a 67/8 8 inch or a 65/6 width 9 inch shoot me a PM.
Yeah.....don't think I would trade for the same gear ratio....plus it is looking like I might need the 9 anyway....and I will just gain back the 1/2 inch I want in height another way. The roller block is headed to the machine shop, the heads get delivered tomorrow, 347 is looking like the number, and there is a big puddle under the ole 67 so its time.
