Engine swap on the way
 

I'll be swapping in an engine from an 83 wagon into my 82 sedan, so I will add pictures as I go, but what should I do as far as the hydraulic pump for the rear suspension? I will be just swapping the engine, no tranny, I know mine works and not sure how well the donor one works and I can't test it because the injection timing isn't set right. will the rear bumper from the wagon fit my sedan? the engine I am removing uses a garrett and the one going in uses a KKK, so can I switch the exhuast manifold and still use the KKK with the garrett manifold?

can I ask why the bumper won't work
