I've made minor repairs in the last month or so to my 1989 5spd:
1). Added new downpipes, and 2-1/4" id to 2" od reducers, using T-bolt style band clamps. Still stock from resonator, back. Slightly more noise, but no drone.
Also to make them fit to the stock exhaust manifolds, I cut the 2" flared pipes off the old ones, and dropped them in 2-1/4 pipes. No leaks!
2). Converted the oil pressure sender to a real one. I had the 20Ω resistor in the harness. Reads between barely to the left of straight up, to the L on NORMAL.
3). Switched the Speedometers from my 1990, to my 89, to correct an inaccurate reading. The 89 speedo would read 18 mph fast, (against my GPS), when cold, then
become more accurate, the longer you drove. I'm thinking bad capacitors, that change with temperature. The 90 one is fast by only 1 to 1-1/2 mph.
4). Replaced the keypad, with an unused one from a 1995-98 Windstar. Got it off of Ebay, cheap. Had to splice the old harness to the new one. The backlight didn't
work, so I removed, (bypassed), the diodes?, on the illumination circuits. Works perfect, now. Has bigger, easier to use buttons, but not as stealth.
5). While I had the door panel off, I adjusted the glass in the tracks, and repaired the power mirror switch. Also, had to replace the seatbelt motor, and module. Clean/lube drive belt.
Driven the old SC 5,500 miles, since the starting with a the engine job, have almost everything working well, including moonroof seal, sub woofer, auto dim, windows, locks, cup holders, etc., etc. I haven't charged the AC yet, but the new accumulator, and orifice tube is in, and it's all hooked up, and under a deep vacuum.
