No, it's not. Macpherson struts eliminate the upper control arm and use the shock absorber (the "strut") as a structural member of the suspension and steering. The steering knuckles would be built right into the bottom of the strut housing. You simply have a conventional MII upper/lower A-arm suspension.
Actually Yes it is, I trashed the upper mchpherson strut, the Spindles, the tiny mustang discs and USED THE MERCURY MARQUIS Aframe and discs and spindles.. the subframe I installed is a mustang unit with lower Aframes and steering rack. The upper Mercury Marquis.
Look at the home-built Top Aframe mounts there. I did about six hours of measuring, drawed them up in cad, then cut the parts with paper templates scribed onto the flat stock. Slotted them on the cnc bridgeport.
This is the top mount I had to make to match the Lower aframe ball joint position with the top Marquis ball joint position.. and yes.. I had a headache that day by the end of the day.. I swung a plumbob, rolled a digital protactor around, levels, measuring.. Finally tacked the mustang lower subframe into the F1 and jigged it around square with a hammer...
Here is a picture of the DONOR car.. the Mercury Marquis, one owner that belonged to my dad.. the 5.0/auto is sitting in the old truck right now, but I really don't care much for it. I got a HO5.0 and 5 speed I want in the truck.
What is really wild, After I torched out the original axle, I had the struts/subframe hanging from the spreader on a chain hoist, lifting all "that mess" into place under the F1 frame.. Tried to set the Marquis wheels onto the mustang spindles and rotors to get a visual. it would not fit.. Darned rotors had been "converted" to chevy bolt pattern.. I scratched my head for five minutes there till I figured that out.. This tubular subframe is from a mustang drag car.. it had chevy wheel pattern on it's rotors, the racer must have had a set of chevy drag wheels. I remember them to be ultra-light.. I swapped a old IH cub cadet lawn tractor for the subframe.. (*really) that 's how we do it down here.. help each other out. At that time I had no use for it.. I was considering building a Three wheeled motorcycle (two wheels in front) like one of the toys I saw in florida.
Right now, I removed the 9" rear axle from the truck that was in it when I bought it, got a bronco rear axle in it right now.. The spring hangers were right, but the wheelbase seems like the tires-rims will rub the bed..
I'd like disc convert the 9" and put it back in the old truck. Or there is a quick change a guy has in the next county.. which I can't afford.. right now.
I checked for bump steer, could not see any.. with the engine/trans sitting in the car the tie rod is a little below level.. God help me if it does not work going down the road.. I got camber slotted adjustment ability built in in and out, on the mercury they swivel the top aframe to get caster in and out.
