Question regarding 67 GT 500 - 31 Spline or 28 Spline

[rbarkley]

Greetings All,

I am sure that this has been discussed numerous time before, but what was the standard axle in a 67 GT 500 Auto?  I have a 31 spline in my Jan built GT 500 with auto trans.

I just added a Yukon posi, so looking forward to having it all back together for a test drive!

Thanks

Ron

Are the housings identical regardless of spline count?

Yes but there is a '67 banjo.

Yes ,but there is a early and later housing (big surprise in 67 ) . The early style has the fill plug in the back side of the center in the housing and that changed sometime approximate May of 67 to no plug in rear end housing . The fill plug was now in the center section (that started before the plug disappeared in the rear end housing).

My car, 3074, which has a June build date HAS the plug. Your witch doctor has not made any progress with me being a contrary lately Bob. You need to have him do another round with me? Two steps forward, one step back.

My 68 housing has no fill plug. That's a February 68 build date. That's a contrary car too. I've had one "68 Concourse Judge" tell me it's not a real Shelby too.

Obviously I'm the problem here.

I was ready for the ambush that questions like that bring.  Not everytime but this time. You overlooked the words  "sometime approximate" . That gives the wiggle room needed to cover the anomalies in this case . I wouldn't have written it that way if I didn't expect a few.
