Maintenance / Reverse lockout and reverse lights issue

« on: September 30, 2024, 12:09:25 AM »

Today I was sorting out my reverse lights on the car and ran into an issue. The car has headers and the linkage for the reverse lights has been removed. Found out my reverse lights were just missing bulbs. I put them in and the lights came on when I turned the key. Great right? Here’s the issue….the lights are on when I have the arm or lever thing on the bottom of the steering column pulled up(clockwise), when I push it all the way down(counterclockwise) the lights go out, but then my key gets locked out and I can’t turn it to LOCK to remove the key. If I leave the arm up(clockwise) the lights are on and I can remove the key. Anybody have a clue what could be wrong here, it seems like something is backwards here?

Thanks, wasn’t sure if it was missing but as it stands I think my column needs a rebuild for other reasons besides the gap, thanks again for the info

Restoration / 1969 Steering Wheel Hub

« on: August 03, 2024, 12:15:48 PM »

Wondering if anyone knows what I need and where to get a steering wheel hub for the standard steering wheel. I just switched from an NK1 back to a standard wheel but now I have a big gap between the wheel and column. Looking at other cars with standard wheel it seems I’m missing what looks like a hub to fill the gap. Here’s a pic to show what I’m looking for on another car. Thanks in advance

Restoration / Y Duct revision

« on: March 16, 2024, 12:00:11 AM »

Question about the defroster Y duct on 69. Just pulled mine and it is part number 3949974. It is the original. My car is a 4th week March car and in the assembly manual GM introduced a new Y duct in March of 69 part number 3973729. My duct openings don’t meet the dash cutout properly and am wondering if anyone has any insight into GM’s March cut in 3729 duct. Was it a better fitting duct? Wondering if I should replace mine with it if that’s the case. Thanks

Yes I’ve learned recently of Fred Ballard and the work he does. Nice stuff I have to say. You’ve helped me a great deal Joe I really appreciate it. Now I know what I need to get, that’s half the battle. Many thanks

Thanks Joe, interesting stuff, so is it safe to say the one I have is a knock off due to not having the AC logo? Asking because I have to replace it and dont want to throw anything away I’d kick myself for later.

Originality / Fuel Pump original?

Quick question about my fuel pump. It has the part number 40727 on it however it doesn’t have the AC Delco logo, instead it looks like it says D5 on the side. Curious as to whether or not it’s original or a Chinese knock off. Thanks for any help it’s appreciated.

Problem solved. Previous owner used the factory resistance wire to the coil coupled with reversing the wires positive and negative. Ran a jumper from coil positive to batt positive, car ran great. Resistance wire delete in process. Thanks for all the replies and help with this. Case closed.

You mention there is a red wire coming from the distributor, as well as a black. That in addition to your comment about a Flame Thrower coil, would suggest there is a Pertronix pick up in the distributor. IMHO, that would be the FIRST thing to get changed out. Others may have different thoughts, but those pick up's have proven to be very troublesome in my experience.

Tim

You would be correct in your assumption about the pick up. It is an Ignitor 3 pickup inside the distributor. Appreciate the feedback on it as I have 0 experience with this pick up.

So I straightened the wires out and she’s running again albeit the same as before. Atleast my coil wires are correct but I tested my coil which is a Flame Thrower .32 Ohm but I’m only getting .1 ohm. Connected +batt direct to positive on coil but the surging continued. Gonna swap it out for a new one and see how it goes. I’m still leaning towards the carb being the issue. Thanks for the replies thus far.

Ensure coil is not hooked up backwards. It will run that way, but poorly.

So the black wire from distributor was going to positive on the coil and the red wire from distributor was going to negative on the coil so I swapped them and now the car won’t start, hmm…

Maintenance / L78 Rough Idle and Stumbling

« on: December 03, 2023, 04:50:09 PM »

Need help with a 69 L78 having rough idle as well as stumbling when I hit the gas. RPM’s fluctuate at idle 200 rpm up and down. Raise the rpm’s still fluctuates but not as much.  Acting like a vacuum leak but I’ve checked all of that including going around with carb cleaner. New cap and rotor, plugs(when I pulled the old ones all of them were wet)fuel filter, Pcv, carbs been adjusted including accelerator pump. Carb is a Holley 4346. Timing set to 18 degrees total 36. Any thoughts as to where to look? Thanks in advance
