OK. Here is the deal. For anyone who is considering converting their '64's power steering to use the Borgeson 600 steering box (with the installation kit). Yes, all the parts will bolt into place, but be aware that some 'engineering' will probably be required AND the results will be almost as advertised ....almost.
If you use your original power steering pump you will discover that male/female connections with the supplied hoses won't connect until they have been changed or modified to connect to the pump or you can buy a later model pump. Ecklers will sell you one with the 'kit'.
So much for the approximate 8 hours installation time.
Next, you will probably discover that the power steering pump belt is too long because the pump contacts the steering box while tensioning the belt, so now you will need a 1" shorter belt.
Once all the parts have been installed and a COMPETENT alignmnt shop has propely alighned the front end you will find that the steering is quicker, feels better, and is more precise exactly as advertised ....until you start driving over dips and uneven surfaces and encounter bump-steer and wandering.
During alignment the driver's side tie rod had to be lengthened extensively to get proper toe-in. This is because the pitman arm is now over an inch higher than originally, which raises the drag link/pitman arm attachment over an inch which raises the driver's side tie rod/drag link attachment which now changes the angle of the driver's side tie rod to the steering arm. Whew! That in itself wouldn't be TOO bad, but since the idler arm/drag link attachment at the other end of the drag link is now over an inch lower in relation to the pitman arm/drag link attachment, there is now a significant difference in the angles between the left and right tie rods. This difference in angle results in a difference in toe-in between the left and right wheels as the suspension moves up and down. The greater the up/down travel, the greater the difference between left and right toe-in changes resulting in bump-steer/wander.
Now an inch or so may not seem much in terms of orbiting satelites or tide cycles, but it is significant on the length of your nose or your car's proper front-end geometry.
I found an interesting forum ( http://www.chevytalk.org/fusionbb/sh...hp?tid/311422/
covers some of the 'issues' (a.k.a. 'problems) encountered during this Borgeson 600 conversion mostly dealing with alignment and is possibly worth reading.
The steering will NEVER be correct until both tie rods have the SAME drag link/steering arm angle! A larger front sway bar WILL tend to reduce the bump steering and wandering by reducing the left to right up/down travel difference, but the ONLY way that I see to correct this problem is to lower the pitman arm/drag link attachment with a drop pitman arm that, so far, I have not been able to locate ...if it even exists. I will pursue this further after the week-end.
Oh, and one other note for those who are considering this conversion, ....something that Borgeson fails to mention is that the lock to lock travel with the 600 box is less than the OEM box. You will need a bit more pavement to make a U-turn.
