hi for some un known reason the t series diff and shaft i bought (seperatly) didn't marry up for length the original ae71 with a t-50 shaft was the right length i just had to get rid of the flange on the shaft so it fit on the yoke at the diff then drill two new holes in the ae71 shaft and touch wood its all still going fine after 6 months and now 4agte conversion
thanks Brendan
