Thanks fo rthe input on the towers - I'm going to just go ahead and swap out those towers.. what's another month?

OK - but regarding the "Shelby Drop Mod" I've read about since.. well since I first picked up a Mustang rag 10 years ago... but only read recently about while that mod improves cornering and "performance" it can also aggravate the already bad bumpsteer issue since it hinks up the geometry a bit.

Read this in the new "Ford Restomod" book and I'm wondering if anyone who's done the mod can confirm this and if so - how they worked around it? Went to improved front end components or added rack n pin?

Well.... I also went with a total control manual rack. I haven't had any issues with bumpsteer. It does have a limited turning radius that's annoying in parking lots and such.
That said though, I wish I had done a Mustang II conversion. It would have opened up the engine compartment and given me a better suspension, brakes and steering all in one shot for about the same money or less.

There's bumpsteer correction kits. My local Mustang shop carries
them, and they are manufactured by Pro-Motorsports. The kit
essentially re-locates the outer tie rod downward with a spacer that
bolts to the spindle's steering arm.

The other issue with the 1" .. or more.. drop is since it changes the
angle of the A arm, it's possible to have the balljoint run out
out of travel under full compression .. when that happens, the
ball joint can break.

When I had mine done, they cut and welded the end of the A Arm
to correct for the angle change when the A arm is lowered....
Also, Pro Motorsports sold a "negative wedge kit" to correct the angle.

If you don't care about originality, just use an aftermarket
A arm from TCP or GW....

Just my 2 cents but I did the pro-motorsports neg-wedge a-arm relocation
kit 15 yrs ago and I have to say it is the most satisfying mod I have
made to the car ( 67 coupe). I wouldn't own an old mustang without
doing this mod, the stock suspension is just plain scary. Anyone who's
had to do a panic turn to dodge debris or another car pulling out
without looking will know what I'm talking about. I never did the
bumpsteer mod and haven't had a problem.

I did the 1" drop on the Falcon and never did any negative wedge or
bumpsteer correction. The car drives fine and has since I did that in 1994.
Will do the same to the Mustang since the front end is apart. The Falcon
spent plenty of time on the street with that fix before becoming a drag
mostly car.

Mail From: wal (Wal Marshall)

I dropped the upper arms on my 70 by 1 inch. Details are here

nzmustang.com/TechData/armdrop.htm

During the job I investigated the angles at the top ball joint during full bump and rebound, and found the joint was nowhere near binding for the joints fitted (which was an aftermarket replacement). However if you drop the top arm more than one inch (1.5 to 2 inches is common and Ive seen closer to three on some race cars) then I would agree the ball joint will bind and need a wedge packer to realign it.I did no work on bump steer correction as none is needed.

However when i fitted the TCP rack...THEN I needed bump steer correction big time as the steering angles were seriously altered. Interestingly (at that time at least) TCP said nothing at all about it, even though the problem was really serious.
