I believe that was just an offset spacer. I am not sure it will work or not, so ask people & see if it will fit to be sure. His spacer moves turbo up & outwards.
You could use spacers on the engine mounts to raise engine & clear the steering shaft.Not my first choice,but would work.
Install a rack & pinion steering set-up.
The 3 spd saginaw trans has poor gear ratios,,, but, if you must. Last thing, sometimes our 6's are not the fastest as compared to those V-thingys, so putting your car on a diet is always good.
