Early Defender Servos

[TeriAnn]

I have identified 2 different spacings for the mounting studs on pre-ABS early Defender servos

There are Defender pedestals and servos that have 8.5cm X 6.5 cm mounting stud spacing. And there are Defender pedestals and servos that have a 14.25 cm X 9 cm mounting stud spacing.

My questions are:

1. What years used type 80 servos that has the 8.5 X 6.5 CM spacing? A factory LR part # would be helpful.

2. What years used the pre-ABS type 80 servos that has the 14.25 X 9 cm spacing? A factory LR part # would be helpful.

3. Do all the type 50 servos have the same mounting stud spacing and what is the spacing?

I'm trying to get some additional information for my web page on power brake conversions and upgrades.

Thanks
