I’ll just leave this right here…

It's not in the chassis yet. The K-member to rear trans mount position is not established. And the T56 doesn't use the factory rear mount. That might be another source of difference between stock A833 and your T56 position.

Not sure if it's going to get any better. But it very likely could change from where it's at now.

What size TTI headers are those? 1 3/4" or 1 7/8" ?
