M3 P/S Swap

Hi everyone,

New to the forum, so please forgive me if I'm not up to speed on the correct etiquette. I have a 1952 Mercury M3 with a flathead V8 (I believe it's the 239 - Canadian truck) that I'm basically keeping exactly as I found it (exterior wise), but am upgrading some of the creature comfort items. I am adding power brakes which I have a handle on, but I would like to also add in power steering. I've seen in some of the threads that there appears to be a Toyota swap over of some sort. I can't find the details on that option, and I was hoping someone could either tell me more about it, or direct me to the correct thread that explains what vehicles from Toy will cross over to this one. Thanks for you help!

Welcome to the forum!

Yes, your M3 will have the 239 Ford engine, unless someone has changed it along the way.

The Toyota PS swap involves a specific range of years of Toyota 4x4 boxes, and there are a couple of aftermarket boxes sold by vendors. Unless you are going to be running fat tires, you really don't need PS, in my opinion. I am running 235/75-15 and no complaints. The problem with adding PS to a flathead-powered truck is mounting a PS pump to the engine. Several people on here have fabricated their own brackets that use the head bolts to mount the pump. I'd suggest just googling "flathead PS pump" and "toyota PS conversion", it should pull up all the threads on the process here. I don't recall a dedicated thread on here that covers everything involved.

Much appreciated!

Thanks so much for the quick reply! I will search further and make my decision. Haven’t driven the truck down any significant roads or distance, so will try that first before going down the road of installing power steering thanks to your suggestion.

Here is a power steering pump and bracket kit. I don't know what brand it is or anything about unisteer.
IMO think it needs an earlier style pulley to blend with the old '52 look.
Pump and bracket for flathead
