Can anyone (esp Bergman) comment on KD's length install issue from post #67? Has anyone else had this issue when using the Bergman coupler that I plan to use? Mine is a '68 B body with collapsible stock steering column. (KD - I hope it's ok we keep your thread going with these questions...)

Our coupler length is based on the EXACT length difference between the Borgeson box and the OE power box. This is a constant. Even with slight differences in coupler body lengths, this is never an issue. #67 seems to refer to getting an alignment after the box install. Since it's impossible to replace one casting with another exactly, you must at least check the toe before driving after the box is installed.

how do I know if I need the small sector box or the large sector box?
The small sector was 1972 and older cars and C body models.
Regarding the length of the steering shaft, I simply figured that the plastic shear pins just got old and brittle and did break, allowing the shaft to compress slightly.

Small sector until 72. Large, 73 later.

They aren't shear pins. There is a groove on the inner shaft that liquid nylon was injected through a hole in the outer.

I thought that I read that Rick Ehrenberg referred to them as "shear pins".

my stock coupler has a round hollow metal roll pin (also called shear pin). Are we talking about the same thing? Or do you mean for the collapsible steering shafts some other internal pins?

The term that I referenced is not related to the coupler. The shaft within a shaft is where I am referring.

Its best to measure the shaft size between the Pittman arm and box. The parts swapping over years, like a reman box, leaves you with the possibility of not having what it left the factory with. With the cost of shipping today, save your money and measure it otherwise you pay for freight twice.

This is what I thought. During assembly from the factory, the slip shaft needed to be held in place. The nylon accomplished this. When properly installed, the tiny anti pullout pin on the side of the coupler and the snap ring and e clip retained the shaft at either end for safety.

I have the engine, transmission and K member out of the car now but I didn't have any of the reported noise from the steering box or pump.
Regarding the Fast Ratio arms, I purposely removed the ones that I had to avoid the dramatic change of steering ratio that they would give.
Stock Mopar steering box is 15.7 to 1 and approximately 12 to 1 with the F/R arms. The Borgeson is 14 to 1. The F/R arms likely would convert that to below 10 to 1. To me, this seems too tight and more likely to feel twitchy and too fast for me.

I concur with KD. I used to run the Fast Ratio arms with my Firm Feel Stage II. Turn in response was much improved, but it sometimes felt a bit twitchy on off-ramps and steering effort increased dramatically (not quite like manual steering, kind of in-between manual and Stage II Firm Feel). Due to the ratio change with the Borgeson box, it's not recommended to also add the Fast Ratio arms with it.

For those that asked about the angle that the steering box has as installed, here is a picture.

In short, yes, there is some angle that it sits at but I couldn't tell you how much of an angle....maybe 2 or 3 degrees??

I just realized that I didn't really explain how I felt about the feel of this steering box.
I was really impressed. The car didn't feel like it wanted to wander like before. The center slop is gone. The steering effort is much easier. I was used to the high effort that the Firm Feel stage 3 and the longer steering arms delivered. The turns lock to lock are about 3 1/2.
I did expect the steering to feel a bit heavier but I was not disappointed with it. Since the car has a 5 speed, having the steering a little easier to operate is a good thing. I want to teach the wife how to drive a manual transmission so this will help.
No leaks, no noises. I still have the Saginaw pump. In fact, I am currently switching to a hydroboost brake system that uses power steering pressure to assist the brakes.....
