Where is the best place to connect a mechanical oil pressure gauge? Right now it's mounted on the passenger side of the block at the front where the factory oil sender appears to be. I would prefer the oil line for the gauge to be at the back of the block. Are there any oil plugs there? TIA.

Does anyone know if this black outside trim for the driver's 1/4 window is available? Also, how feasible is it to have the trim replaced without breaking the OEM window? My trim piece is warped at the top of the window on the driver's and I wonder if that was a factory issue. The passenger...

Has anyone tackled this project? I see complete kits for sale, but I would not attempt to add it if it meant cutting up any wires in the harness or splicing in to power wires for a 12volt supply. I was hoping GM had the wires in place for all G-bodies and you could just "plug and play", but...

E-bay. 8036941729 Expensive, but not if you needed it. I wonder if it bolts in to a GN?

Left bank exhaust pipe connects to the right bank (cross over pipe). Should there be an exhaust clamp at that union? Drove car for the first time ever tonight and that union slipped apart @ 3/4 throttle. (Boost was non-existent once they came apart.) Previous owner had the manifolds...
