whats the redg number I may be able to help, and make and model of car.
Sorry, This is a bit convoluted but stay with me. I have a WRX diff in the back of my Subaru Brat. I have learned today that the original shafts might be too short now, as I used the WRX inner joint cups, and I have had one outer joint pop out which backs this theory up. I also learned today that on EA82 (Loyale / Leone early / mid 90'S) rear axles, the inner axle cup from them can be used in place of the outer on the my Brat, and as it's deeper, so will allow more axle extension. So random Leone number stolen from the net - G774 VEV I really only need the inner cups but presume that it will have to be the complete shaft.
