I still needed an exhaust. Yet again, Shane hooked me up. These were from an 87 longbed.
Price was free. I can afford to do some work for the money saved.
87 model exhaust used larger flanges than the 78 model did so I had to cut the ends off and replace them with the original 78 era parts. Not pretty, but free.
The rear tips were all wrong for this truck and bed so I just cut them off into shorter dumps. Built a little frame crossmember from an old scrap stepside bed cross sill and some hangers from Rockauto.
Total investment in the exhaust is probably 30 dollar including the clamps, hangers, and donut gaskets.
