About the Hedman shorties - in my 79 GP, I am using the 28164's. The pass. side slid right in. The drivers side header would not clear the frame. I cut off the collector as close to the tubes as I could get. Then I welded on a new collector made from 3" tubing that I cut at an (30 degree, I think) angle. After that, and a bit of massaging, it fit.

I fabricated my down pipes from 3" Summit U-bends, and the ground clearance is excellent, which is the whole reason I decided to go with shorty headers in the first place.

So, for future reference, the 28164's are NOT a direct fit on the drivers side. Perhaps the 28170's would fit better, but I can't say. If someone else has tried them, please let us know. I'm curious.
