Hi All,

Probably a silly question but I have to ask.

I'm looking for a RHD pitman arm to suit 1955 chevy.

I got my hands on a complete drag link with pitman arm assembly only to find out that the pitman arm has been modified to suit a Ford steering box so I'm needing a pitman arm to get me out of trouble.

Any help would be greatly appreciated.
Cheers!!

Hi Ange,

Thanks for the reply mate.

At present the pitman arm was used with a Ford Steering Box and when installed on a mazda steering box (being used for the conversion) it is sloppy.
The mazda steering box shaft is the same size as stock chevrolet so I'm assuming the pitman arm was modified to fit the Ford Box.

Cheers!!

there have been lots of conversions done here over the years. One i saw recently was a cut and shut lhd drag link. The right side end was then cut and threaded to take the Ford Falcon end - similar to the original lhd Chevy PS drag link. This set up used a Ford PA and a HK Holden steering box. All mods were done by a blacksmith and xrayed to ensure no crappy welding.

Another conversion done here was to use the original PA and graft in the inner splined section of a Toyota Crown PA, and the Crown box. The way I heard that it was done was to cut out the Chevy PA around the spline, do the same to the Toyo PA and join them together - by welding and pinning. That way you had a Chevy PA with Toyo spline - again best left to the experts and some xrays after the mods to ensure no cracks etc.

Thinking outside the box, it would be possible to use a lhd PA to restore a rhd one by following the same methods as with the Toyo conversion.

Cheers, Des

P.S. I don't have any rhd steering parts atm - they keep bobbing up though.

Garry, if you don't use the butchered pitman arm and want to move it on, I could be interested as I am looking at using either a jeep, a Montero (Pajero) or a Range Rover box.

All of those have larger diameter sector shafts than the Trifive so re-splining, yet again, is an option (provided the Ford spline is not already too big for those.

And..... it would negate the need to mess up another RHD pitman - if I can find one (no, I wouldn't do that, I'd get the sector shaft re-splined to suit the Chevy pitman).

The Mitsubishi Pajero / Montero box isn't a good candidate for RHD Tri-5s

The Steering Box was designed to mount "outboard"[RHS] of the frame rails on the Pajero.
They are a very good candidate for a LHD Power steering box. I have successfully used it's little brother [Mitsy Sigma/Starion RWD] on a LHD Corvette C3 to eliminate the Ram P/Steer.

Thanks for the update, sounds like there`s going to be a shortage of sigma boxes :)

Look at an Isuzu Bighorn [Holden Trooper] steering box.

It is almost a reverse casting of the Mitzy box making it an ideal candidate for mount inboard on the RH frame rail.

Most of these Jap steering boxes are made by Aisin

Was talking to a mate yesterday who is fitting power steering to his 63 Chev , he tells me the RHD Jeep Wrangler 1993-2001 vintage has a steering box near on identical to a 63 chev manual steering box , even bolts up using 2 out of the 3 original holes and just slotting the third , might be worth a look ???

Are you suggesting that Jeep box for a tri5?
If so, it's way too short. The early 60's Chevy box is similar in size to a HQ Holden and the tri5 boxes are a lot longer
Cheers, Desmi

RHD power steering box

Hi guys, I manufacture right hand drive power steering boxes here in Melbourne to suit the 55-57 Chevy. I use a Delphi 600 Series power box and modify it so that it will bolt straight in to the RHD chassis, using the factory mounting holes. I can supply it with a 1-1/8" spline to suit the factory pitman arm or with a 1-1/4" spline to suit a RHD pitman arm that I also manufacture in Melbourne. I also supply the correct steering shaft and rag joint to suit, plus have Saginaw pump, bracket and pulley kits to round it off. All of these parts are top quality Borgeson products. I have sold over a dozen of these boxes and have had only one complaint, which I quickly rectified.

Regards from Down Under. :bowtier:

Blacky,

As for your friend's '63 Chevy, the Jeep box has no holes anywhere near close enough to mount it to the Chev chassis and make it steer correctly, however, I have had made a bunch of adapter plates to fit a 1965-1969 Chev/Pontiac POWER RHD box to the 1958-1964 Chevs. This box is a Saginaw 700 Series box and is more than strong enough for the job. The plate bolts to the box with countersunk bolts then the plate is bolted to the chassis using the factory mounting bolt holes. Due to the bigger diameter sector shaft, I have had made a bespoke pitman arm to suit the sector shaft. I also supply a Borgeson rag joint and intermediate shaft to connect to the stock steering shaft. I've sold over a dozen of these kits and they all work just fine. Call me if you want to know more.

Regards from Down Under. :bowtieb:

Hi mate,

Thanks for the reply.
I'll find out. This was for a friend of mine doing a conversion. I'll get in touch with him tomorrow and see if he was able to find one....otherwise I reckon he'd be keen.
Will be in touch.
Cheers!!
