I went to Speedway motors tonight here in Lincoln NE and talked to a counter guy who ownes a 51 5 Window and has done this upgrade. All I needed was comon 3" spring perches they were only $12.49!!! A far cry from $140 They also had a inclonometer for $10 to set the pinion angle, for those of you that don't know you want the pinion angle to be the same as the angle of the tranny output shaft.

If you need a tool and don't buy it, you will find you have paid for it and don't have it.
