has anyone thought about replacing the stock lower suspension control arms with the aftermarket tubular A-arms and removing the strut-rods? If you have done this, what modifications have to be made to the cross-frame?

I believe if you look closely at the manufacturer's info, the wide tubular lowers are not recommended for use with the stock crossmember, and the narrow style tubulars require the strut rod.

Using the wide tubulars with no strut rod on the stock crossmember is very much bad... The crossmember isn't quite strong enuff...

what if the crossmember was strenghtened with steel plate and boxing it, do you think it would work? I agree that without a tubular A arm the strut is required. I'm looking for more wheel clearance and removing the strut junk that protrudes into the area between the frame rails. I've moved the firewall back 10" for engine set-back.

I actually have been thinking the same thing myself... If reinforced by some means I think it would work..

I've been looking at the street rods front cross member this last weekend and they seem to just thicker side sheet metal. Do you think this would be enough?

Why not do what the Hotrodders do to hacked out MII IFS. Box the factory arms with a plate of sheet metal welded to the bottoms.That would allow you to trim off the lip around the arms in install larger dia. disks & rims.

that would work for the disc and rims and be a big improvement, but I'd still have the strut rods in the engine bay area. I've been thinking that I maybe able to shorten the threaded length on the strut for more clearance in the engine bay and cutting down the strut mounts size. I would like more side to side engine bay clearance since I've moved the firewall back 10" and the engine about 8". I'm looking for header and starter clearance.

The 91-93 ponies with a 205 will work without modifications. my 225s rub in hard corners. The rear actually could stand to be about 1-1.5" wider

cobraman, so your saying the front 225 tires rub against the frame at full lock? What's the back space and rim width on the 91-93 pony rims your running?

I took a stock mustang II and put tubular lower control arms on it. First I bored out the lower bolt hole to 1.25 dia and then took a piece of round stock 1.5 dia actually for those that work in machining it was a 1.5 boring bar shank a little over 7 inches long. I drilled a .630 hole through for the bolt and turned down the width of the lower control arm so that it just stuck out the other side a little bit to weld to. Then i welded it in and put a support to it for strenght. As you can see in the pictures.

6TFalcon I can't get to your pictures. Do you have an website? I can't get into the one you've listed. So how well does the front suspension work? Any twisting or stress to the cross member?

thanks falcon, the pictures worked this time and you're right. The do tell a 1000 words. I think from your example I have my answer. Seems you have no strut rod. The picture doesn't show one or if you added one later.
By the way, the Falcon looks like a fun little ride. Nice work.
