[Alfar7]

All have the same input shaft splines. All will bolt up. The shift issue is only minor. But the speedometer drive is dependant on the year & pinion shaft end design. If you have an earlier model the end is a "gear tooth" drive. Later are strait slot for hall effect pick up.
The LSD can be fitted in any 6 cyl. case. The best easy change of all the ratios is to use an Alfetta input shaft & gears on a 6 cyl. pinion shaft with the LSD fitted. think the info below is on my website and was posted in the BB earlier. The final drive is the least important consideration as the performance depends on ratios lower. All the 6 cyl. boxes were designed for economy.
