LQ4 in a 1971 Nova
If you don't find the answer on the headlight bucket springs in the meantime, I will see if I can somehow take photos of mine later tonight.
Is your steering disconnected or toed out for some reason? Or is that just the photo and some normal akerman going on?
You can get a decent look at the spring by removing the bezel, but it's not a HUGE deal if you don't care to.
My 105-amp LQ4 alternator has one wire, to the L terminal only: this is the alternator turn-on signal from the PCM (red connector pin 15 for the 99-02 truck). The S terminal, which is used to sense voltage to be controlled via the main distribution point, wasn't used at all. Based on GatTagO's advice, I wired the S terminal using a Metripack 150 connector like that shown below. I had to do some quick dremel work to make it work due to the fact that the alternator plug is keyed, but it was otherwise plug and play. And wow, I'm finally seeing 13.5+v regardless of load, all for about $12 and an hour of my time.
From the alternator bible linked above:
...I consider it crucial for good performance that you also wire up the remote voltage sensing terminal. To do this, connect the S terminal to the vehicle electrical system's main power distribution point (bus bar, main switch, fuse panel, etc.). If the S remote voltage sensing terminal is not connected, the voltage regulator will revert to internal sensing of the alternator output terminal voltage - with all the limitations that brings. You will see some alternators wired with a short jumper wire from the S terminal directly to the battery connection at the back of the alternators, but this is neither the proper method for remote voltage sensing nor necessary for internal sensing - do it properly or leave it out.

It topped 210° yesterday coming off the freeway, in 102° weather with the AC on high, but came back down to ~205° after a couple minutes on surface streets. I watched the temp gauge like a hawk at the light, but it wasn't ever concerning. I wired up a manual switch for my high-speed fan trigger last summer when I thought the PCM/trinary switch weren't triggering it; I flipped it on with no voltage drop, which suggests the fan was already on high. I'll be eliminating it in the coming days. I plan to continue driving until failure, which isn't out of the realm of possibility as we still have another 15° to climb. So I'll hopefully be able to declare victory in August.
Your avatar is dated now with the old master/booster combo, yellow radiator hold-down panel, and cross-over coolant hose. The engine bay is looking super clean these days.
The plan is to take the axle completely out of the car and have it looked over by a shop for straightness and general condition, plus finish welds.
Second you suck! I'm jealous as hell of that box of goodness I hope the install goes well and both fitment and performance are as good as I've heard.
Third the new avatar is great!
The Best V8 Stories One Small Block at Time
One thing the boys have constantly complained about is the fact that my rear windows don't roll down all the way. I have a late-71, and it seems that somewhere along the line they changed them over to only roll down 3/4 of the way (along with the front bumper lenses going amber and tails going with a square reverse light from rectangular). I had a set of regulators from when I thought my front was bad, and decided to check them with the interior out. Lo and behold, they were different! The early-style arm (right) is lower on the gear - note the arm in relation to the gear teeth. The cool thing is that you only need drill out a rivet and move the arm to another hole to do this mod yourself. I now have a new headliner, door panels, and rear windows that roll all the way down.
With that done, I'll shortly be moving on to the good stuff...

That's an interesting discovery on the regulator. On my 70 I have one side working and it goes all the way down but it can get bound up at the bottom sometimes. I wonder if they changed that so it wouldn't lock up at the bottom.
It’s possible they redesigned it to eliminate ate binding. I put white lithium grease in the forward channel and they roll effortlessly - my passenger side was stuck before.
Hope things are going well with #3. If you don't have a minivan yet, you don't know what you're missing out on!
Can either of you guys point me to an install/tips/tricks thing for headliners on our cars? Or anything to look out for in general? Maybe I'll just wait for Clint to do his and create an in-depth write up on his build thread... the headliner and sail panels are the last things I have to install in my interior.
So, just my .02 cents, I paid an upholstery shop $200 and it looks amazing. He did a great job, steamed out the wrinkles and it was all done while I was out on my boat catching fish! No awkward time with my arms falling sleep over my head trying to clips and windlace to hold up the headliner. Not ever fun paying someone to do the job but it was done once and done right.
Also, they will match the visors and sail panels to the head liner, another detail that is important
I called a shop to do another car, and they quoted $1,500(!) to do it. Granted, it was a wagon, but that drove me to attempt this myself - worst case, I’m out $55 and a few hours of my time.
Just a quick update.
Nice to see the rear coming out. Are you planning to use the same axle assembly and just remove the old brackets? Any changes beyond just putting the torque arm system in there? Feel free to text if there's anything I can help with. If I were closer I'd help you wrench & fab.

Once I got everything back (including powder coat for the Speedtech parts), it was time to go back up with it. Years of pinion seal leaks left some serious grime on the pumpkin, so the boys and I cleaned and repainted it before assembly.
Installation was surprisingly easy. I had to cut off a bracket on the forward and to the driver's side of the fuel tank and remove the rubber pinion snubber , but otherwise everything went together well. Sadly, the panhard bar was machined incorrectly, so Speedtech are sending a new one (hopefully) next week - you can see that the axle isn't centered laterally at the moment.
I included a check list below since I know you all love them so much. Once back down, I'll need to have the alignment checked to ensure the wheels are square. I will also need to whip up an H pipe for the exhaust, as my X pipe hits the torque arm.
