I don't know if this is the right place to mention this....

But for you that have old BIG bolts with air brakes (aka an air system) and you want power steering, the old style air assist steering is still available new.

All that is available now is a 'universal' kit. You cut the drag link (excuse if I get the terms backwards, I get drag link and tie rod mixed up at times) and weld the air regulator there that controls the air cylinder. The air cylinder then mounts to the tie rod and another end is mounted to a mount bolted to the spring bolts. (A lot of factory hydraulic systems were set up similar.... kind of like the old Ford C series power steering, with the cylinder under it instead).

I put one on an old '77 KW K100.... I got lucky, an old stocking dealer had the drag link kit for the old K100. Who knows, maybe.... some stocking dealer might have old drag links for the Bolts. Company has been around since the late 40's. The system is by Maradyne called the Air-O-Matic.

Like I said, I hope this is the right spot to let ya know.....

Edit-
I scanned and 'archived' the install instructions to PDF file. If anyone is interested I can email you a copy for your any of you that are curious.
