Mustang II isntall

Post #1 by cobraguy » Mon Jul 16, 2018 5:27 pm

I got a deal on a complete 75 Mustang II front end. Donor was a V8 a/c car. I grabbed the master cylinder and proportioning valve with it. So now I have a couple questions right off the bat. Strut rod mounts. Sway Bar links using Falcon bar. Spring rate-springs have been cut so I'll be getting new ones.
Thanks Rich

You will need a Fox sump for a 3.3 or one modified to fit your 250 like Mike1157's

For mounts, you'll have to compare the Fox IFS to the Mustang II one, and make up the right offset for your Falcon.


The Falcon Six to Fox engine mounts are further forward 4".


So all the Foxes used the stock Mustang II postion, but moved them forward 4"



Here is Mike1157's I6 X memeber in his 79 Fairmont

Stock 2.3 Four, 2.8 Cologne and 3.8 Essex V6 and stock SBF v8 mounts are located like this.

The stock I6 frame horns are so much further forward

Here are some before being cut back to install a V6 in a six cylinder Fox. Since the Mustang was sold internationally with a Bristish Cam Gears/Adwest patent power steering rack, this one is actually an SD1 Rover RHD steering rack, same as the Austrailan Cortina. Its shaft is there on the Wrong Side. Or on the Right side, not the Left side....duoh!


The Mustang II IFS X member needs the same kind of work to make frame horns to mount the 200 or 250 I6.

So you have to make perches to forwar mount the stock F150 isolators and mounts Ford used on the Fox i6's.


The Fox was designed to use the Mustang II and Australian Cortina rack and pinion steering made worldwide by Adwest and in USA by TRW. So your I6 has to sit where it does on the stock Fox I6 to suit the Mustang II crossmember.

The upper strut can still be used to hold the stock shock absorbers, you don't have to use the MII ones.Its easier to just copy the Mustang 64 to 73 Mustang II swap details for the Modular Cammer engines. The US aftermarket has got that sorted out. A pre 1967 Modular 5.4 dohc swap uses the Heidts Mustang II IRS, so your better off getting some good Been There, Done that Advice.


The Falcon XK 500 frame is what all that later Mustang 64-73 stuff was based on, so get some advice.


There is lots wrong with the Mustang II stuff, but power rack and pinion is front mounted, the front strut tension rods from the Ford XK 500 platform is best replaced by the Mustang ones.


There's nothing munch good in the early Falcon and pre 1974 Mustang Ford a arm over coil front suspension. Because the steering box is rear mounted,which makes the steering promote roll over steaer and the tension rods cause instabilty and because geometry is pretty archiac, your better off with using as much of the M2 stuff as you can.

This is a major exercise involving removing all the existing front suspension, steering, and much of the shock towers.

The Mustang II front sub-frame assembly complete with suspension, brakes and rack and pinion steering is then positioned in the correct location.

Uprights are welded on to pick up the existing chassis rails and thus attach it to the car. The two big advantages are the conversion to R&P steering, and the big gain in engine bay space, (by removal of the shock towers) giving more room for headers and making spark plug changes so much easier.

Check this link. Easiest way to complete the conversion is to buy one of the aftermarket kits now available such as: Rod & Custom Motorsport. http://www.rcmotorsports.net/page6.html

This is a total Mustang II Front End Kit, with manual or power rack, tubular upper & lower A-arms, Fully adjustable coil-overs and has the small or big block mounts.

"I did the research & Rod & Customs Motorsports makes the best Mustang II kit out there for early Mustangs. The beauty of this kit is that Rod & Customs Motorsports has been around for a long time and will sell you everything individually if should you ever need replacement parts down the road. They have awesome tech support and you'll be talking to the owner of the company when you call. Also, any headers that will work for a 79-93 Fox Mustang will work with this kit. Same goes for the oil pan. ABSOLUTELY NO CUSTOM HEADERS, OILPAN, OR STEERING COLUMN NEEDED WITH THIS KIT---UNLIKE OTHER MUSTANG II FRONT END CONVERSION KITS. This kit even includes the steel patch panels to cover the holes where the shock towers are removed."

Thanks for the info and pics. I've done a Volare swap into f-100 so nothing really new here. Same types of challenges. I tore down and cleaned the M2 stuff and found a couple issues. I'll be buying tubular upper arms because one of mine is cracked and the bushings were welded in. I guess the previous installer didn't know how to shrink a the bushing holes to tighten them back up. I've done a lot of mocking up measuring and cardboard test fitting so I know where to cut what and how deep. I know I have to modify my 250 oil pan, it seems the easiest will be to cut the bottom of a fox body 302 pan off and meld it to my 250 then fab a rear sump oil pick up. I have the Scarebird set up on the car now that will be going up for sale when I strip the stock suspension off. Anybody interested in the stuff coming off can PM me. I'll let it go cheap just to recoupe some of the cost. The stock stuff is in good shape and includes 64+ mustang UCAs with roller perches, scarebird disc set up, flipped center link. Don't tell my wife but if an affordable 302 becomes available while it'a apart I may go that route. I think running a second exhaust pipe down the driver side would be easier than fabbing the pan and pick up.
