Aligned the drivetrain.

How did you change the position of the engine? Use a hoist? Or a jack underneath?

Loosen the C-Beam bolts at the transmission and use a 2x4 to lever the transmission tail.
From "The ZF Doc's" website:

ALIGN DRIVELINE COMPONENTS: Take the following measurements directly above and to the right of the Propeller shaft front yolk universal joint. To ensure proper alignment of the driveline, a clearance of 45 mm +/- 6mm (1.77 in. +/- 0.236 in.) must be maintained between the top of the support to the underbody and a clearance of 28 mm+/-6 mm (1.1 in. +/- 0.236 in.) from the right side (passenger side of vehicle) of the support to the side wall.

Good luck!

So, if the driver's side of the engine is too far to the LH side, causing the header tube - steering shaft clearance issue, then the trans tail would need to be levered towards the left, in an effort to rotate the engine/trans assembly? Or is my thinking flawed here?

Okay I know I am very slow on my progress but I am finally getting time to get back to my projects, man things have been busy. Okay I have aligned the drivetrain and that resulted in a rather large shift of the motor toward the passenger side making a good 3/16s clearance of the steering shaft so no mods had to be done to the headers what so ever. I am really pleased with the build quality of these units I also like how they consider that someone would have to install it and gave good clearance for bolt installation. I am now making a set of O2 sensor extensions (is there a length I should not exceed or a optimum gauge wire I should use, I will make them equal length no matter what??). Now I am using stainless allen bolts with stainless lock washers. Should I use the factory torque or should I go a touch more due to stainless being softer and possibility of stretch?

Thats it for now

I have also repaint the flow master exhaust but before I install it I need to clean all the hand prints and what ever grime is left .
