Bergman PS box (Borgeson) and Lares PS box on a 66 Hemi?

What he said.
It's more effort than what I took out. Over powered oe stuff. Additionally, I replaced all of the steering and suspension components, so there is most likely some additional effort just from that. The effort is less than the r&p unit in my 04 Cummins dually, but that doesn't help you most likely. The tech lady was beyond helpful. I asked her about fitment of the unit, especially pertaining to headers. She said if you have stock exhaust, you're fine. Headers, you're on your own. I have Hedman's on the wagon, installed by PO. #3 and #5 had to get thumped. 3 for the box, 5 for the coupler. I also put in a new pump from them which worked out as I had to drop the box in from the top. Took the battery and tray/braces out, pump out, #1 plug out. Pulled the motor mount through bolt on the left side, put a screw jack under the pan rail to tilt it up a little, bingo. From below, no way unless I removed the header. Then I would have had to deal with coolant leaks with the iron head 440. I picked the lesser of the two evils. Along with the box, you need the inlet fitting, which does not come with the box due to differences in years/fitting sizes. If you go on Rock, go to the steering section for your car, hit that and look for "Power Steering End Fitting". Thats the fitting you need for the pressure line. I also installed a filter inline, out of the steering box, followed by a cooler which then heads back to the pump. Also the tech gal told me that Bouchillon has been using the Lares units for some time. Might be an additional info source for you. If you go to Fall Fling, I'll be there with the wagon. You can check it out hands on.

I have the BAC unit for my 65. Haven't used it yet, car is back burnered for awhile. I was going to do the same for the wagon. Kept hearing about the Lares unit here on the forum. Checked the price difference and it was less. Emailed Lares to get some info, then made the buy. I'm watching my expenditures on the wagon, so trying to get the best bang for the buck. Also the 11033 unit has a little faster ratio than the stocker. 11043 faster still. Happy with it so far.

Can't find the ratio, of course, on the 11033. Its 3.5 turns L-L. 11043 does show, on Rock, 10:1 ratio and 2.5 L-L. Same look on the outside for both.

Porsche's steering ratio varies significantly between models, often featuring a variable, or progressive ratio, which becomes faster (lower ratio number) the more the wheel is turned, for example, changing from 17.15:1 to 13.12:1. Some models incorporate rear-axle steering to adjust the steering ratio and turning circle, while high-performance models may use specialized components like a 911 RS Crown Wheel and Pinion with a 8:35 ratio for a significantly quicker response.
