Been a while since I updated this. I ran into a bit of scope creep. I ended up doing a way more than I originally anticipated for just a heater core replacement. The car basically has a brand new cooling system. Fan clutch, radiator, heater core, belt etc. Been driving it for a couple weeks now. No issues so far with it. In addition to the cooling system and MM quadrant, I did a bunch of other little things while the car was in the garage but I won't bore you guys with that.
The MM quadrant allowed me to adjust the pedal a little more off the floor but unfortunately it did not solve my hard shifting into first from a stop issue that happens randomly. I think the pilot bearing is bad/going out because it does not happen all the time and it does not grind at all in any gear. Every thing I have read tends to point to the pilot bearing. I only have the issue with first and sometimes with second when down shifting. Clutch has about 120K on it and the clutch fork cover has been gone for who knows how long so there is a lot of grime in there from what I can see. I got a repro cover now but the damage is done so to speak. First couple days I drove it after its short hibernation in the garage, the first gear thing was bad. I got discouraged and let it sit for a bit again and then decided to take it to run errands one night and it was fine. It has been decent ever since. I am going to change the clutch when the weather gets a bit warmer. Hopefully it stays working decent. If not, I will do it sooner than later because I do not want to damage the transmission.
So now I am working on installing a stereo. The car is getting a bunch of used stuff that I had saved. Only thing I bought new was a set of separates for the doors and dash. The car was a premium sound car. I have the Metra adapter cables but I did not get the kit that came with the plug for the amplifier. I even bought the adapter cables for the speakers so nothing is butchered. I remember reading that there was something that needed to be done to get both the door and dash speakers to work. I will have to look that up again before I get too far with the wiring.
That is all for now
