Just a quick update.
I need to take some photos to update some of the things I've done lately.
1. added a snap tonneau cover. (the car had the snaps and this just helps cover them up as there is no way to remove them without leaving holes.) I made this myself with tonneau material I found on the internet and snaps. It came out better than I expected.
2. finished up the door panels (they look great!)
3. changed out the exhaust manifold gasket. Broke one of the bolts but there was enough sticking out I could use vise grips to remove it. There was virtually nothing left of the old gasket. I replaced all of the bolts with grade 8 bolts and internal tooth lock washers. The new gasket got rid of most of my 2000 / 2500 rpm vibration! And the engine idles smoother. No exhaust smell in the passenger area either.
