I have the box mounted, and I am using the Bergman adapter to mate the box to the column.

Questions:

1. The angle of the adapter to the box shaft looks sorta extreme to me... should it be?? Do I need to shim the box to make it more of a direct input?

2. The splines on the box, in relation to the new slip adapter, does it have a master spline? or is it wherever you put it in relation.

3. The Bergman slip joint looks like it does not use the large factory roll pin like the original, even though it came with one. It looks like it has some sort of sleave inside the internal splines to limit travel. This blocks the cross section for the large roll pin. Does it get eliminated?

Thanks a bunch to anyone who can help, it's going decently well so far!

Call Bergman- he owns, races, and sells these 'kits'. Get it from the Horse!

Yeah...Piss off already !

Kidding of course.
My guess is that the OP probably wants to call, but maybe is unable to do so during regular business hours. Sometimes, guys with experience are lurking around here at odd hours, just waiting to help out!

At the risk of stepping into this quagmire again, do a search on Borgeson box and postings under my handle, or Hotchkis. Likely if shaft is not in perfect alignment with steering box you will be looking at shimming the box in order to obtain proper toe in whilst having steering box on top center.

The shim seen in the 2nd photo was placed there to correct the angle seen in the 1st photo. Without the shim, was impossible to obtain proper toe. This on 70 Challenger.

The adapter spines do not have a master spline to steering box, this permits you to achieve proper steering wheel alignment.

Roll pin is eliminated. Set screw on adapter should point at 9 pm toward driver side of car when steering box is on top center. If not,,,,,again is a clue that steering box must be shimmed when toe is properly set.

I'm interested in the Borgenson ps box... but I'd prefer to install the longer fast-ratio pitman arm (with the longer idler arm, as well).... making the ratio ~11.7:1 vs the T/A = 12.7:1.

The pictures shown above... with the angle of the shaft... is that corrected by adding the shim?

Yes. Until I added the shim I was unable to obtain toe within specs unless the steering box was indexed at about 10:30 o'clock,,,given if you were to consider 12 noon at proper top center index.

This forces steering shaft a straight shot into steering box with no angle created at coupler, which is as should be.

In short, if steering shaft was straight with your old steering box and not so when Borgeson is installed, you may have a problem that will require shimming or other remedial action before proceeding. I had considered several possible options before going with shimming,,drilling 2 holes in 1/8 inch X 1 inch wide X about 2 inch or so long steel stock.

I have since ordered up the correct mounting bolts to replace the incorrect Grade 8 bolts I used as shown in the photo. Threads on original mounting bolts were quite buggered for some unknown reason.

My understanding that Borgeson has now chosen Mustang boxes as the basis of their Mopar replacement boxes. Earlier one's were reconditioned Mopar boxes(Jeep believe) as I understand,,,however they do certainly appear externally different than that in my case on my E Body,,,,am uncertain which Mopar if not Jeep. These replacement boxes are smaller and 15 pounds lighter than stock Mopar box and do clear my 2 inch TTI headers much better. The Mustang box is reputed to be even smaller

Therefore this potential issue regarding shimming requirement may no longer exist.

As an aside, I recently installed Borgeson in wife's 55 T Bird. Outside of the fact that Borgeson does not offer a kit for a T Bird and was forced to adapt a Ford sedan's kit,,,a substantial difference from what a T Bird requires,,,was able to make it work. Likely had some 50 hours of effort and false starts to achieve success. Told by Borgeson tech that this was a first on a T Bird.

Was able to make it work with no Borgeson related issues and very pleased with outcome,,,which incidentally am also quite pleased with outcome on our Challenger,,,albeit a real pita.

Mine needed a shim as well, maybe 1/8" thick. Still worth it.

I added a shim as well. Modified an old rear spring shim. IIRC, a 2 degrees shim placed the shaft close to alignment.

Let me know how well your install goes Mitch!
I forget if you have a small block?

I am considering the same setup and will go for it only if you get good results. Hard to justify spending a grand if its gonna be another PITA

It's a PITA. I'm of the mind that if you have a Manual Car and are going to power, get this box and deal with the hassles. If you have a Power box, just get it rebuilt by Firm Feel and if you want the "Dead Spot" tightened, just have them do the same thing Borgeson does, tighten the lash on the sector adjustment.

As a reminder:
Borgeson units are REBUILT, USED units that don't fit well and require shimming/modification and plumbing retrofits to install, not to mention the rash of Pitman arms we've seen loosen up. Factory units are plug and play.

My box is shimmed...and I have the Bergman installation stuff. One of the best things I ever did to the car. It's NOT the same thing as tightening the lash on the stock box.

Thank you all so much!!!

I do have the newer smaller box (It's tiny) and the angle is opposite of what is in the above pictures.

I will shim the one side and continue on.

Thanks a bunch!

Have seen no postings of installation of Mustang based boxes. Hopefully you will report back on how your installation went and your satisfaction with performance. A couple of photos of finished installation would be a bonus.

Reportably that Mustang based box is less expensive than prior Delphi/Jeep based box. I believe my Dephi box was somewhat over 700.00 plus the cost of a couple adaptive components acqired from Bergman,,,,coupler and hose adapter.

Thank you all so much!!!

I shimmed it as best I could, and the coupler gets close to the headers, but not bad at all. I will get some pictures when I am farther along. I am doing a whole bunch of stuff at the same time, so It may be a while!

Why people dont call and ask me these questions is beyond me....

So provide us some feedback on the differences between the mustang and Jeep boxes? Impression on the changes, etc. Tim
