The GSP is in need of the vacuum harness (plug & hoses) on the rear passenger side of the engine compartment. The hoses run from the vacuum block to the EGR Valve, two smog diaphrams and to a connection at the rear of the manifold.
Old age has caught up and the hoses are broken on the GSP. The attached photo is from my wife's '89 LX 5.0 conv. Please post up or send me a PM if you have a good one for donation or for sale.
