Very very cool ! could you please notch out the frame rail in front of the coil spring, would give you more functionability and adjustmentability on your excellent indoobidibly cool car. I ordered a front end from John too, should have a tracking # by Friday !

if you did it right it would be stronger i think . cut a lil deeper than you need and and it a nice lil triangle. cap the ends of the frame and put a rib in there then add side plates. it'll break all around there before that goes. eighth inch for the flat stuff and quarter inch for the rib. just make sure the rib is shallow enough to be out of the way.curved/bent metal is not as strong as a triangle.

check out model A frames getting "c" notched winds up being stronger than the rest. When are you getting your front end kit from John ?

We wanted to add this IRS brace because the color was so cool we had witnessed some pretty bad "exploding pumpkins" at the drag strip when the 2003-2004 Cobras sent a little too much torque spike down the driveline. We've seen documentation of many mid-10 second passes and even a high 9-second pass with only this brace added. Again, it is a local product, and comes from Billet Flow: It is hard to find this sticker on many products these days!And, again, I'm betting this installation was easier because we had the IRS off the car:

It's coming along real nice.
Is that a aluminum driveshaft or chromoly. I'm not to far from picking up a new driveshaft myself for my new rearend. Wondering what kind that was and what it set you back if you don't mind.
I went with a 1350 yoke also. It's steel. cost me $100 bucks. $150 for the chromoly 1350 yoke.

did you go 1350

No. What is the advantage of using the 1350 slip yoke? Lower loads on the U-joint needle bearings? Or something else? I did not think slip yoke was the weakest link anyhow ... wouldn't you break at the axle before the slip yoke would fail??
