Thanks for the suggestions.

I am reaching that same point. But based on your description I doubt the limiter is the issue. Pulling the front seat makes things so much easier for under the dash work, especially if they're buckets wink beer

That was the first thing I did remove the bench seat. Second thing was lower the steering column. Still a tight squeeze.

30 years ago I could get the cluster out of my 68 Charger in 10 minutes with the seats in. this was after repeated "practice" while calibrating gauges, (Long story)LOL beer

30 years ago iirc I didn't care to much about anything as long as the vehicle (car, truck, motorcycle) ran and got myself and friends to the party. LOL

Update
So I removed the instrument cluster and replaced the two printed circuit boards along with new LED bulbs and sockets for the dash lights. The fuel gauge was tested and found to be faulty. Replaced with another used one that tested good. Bench tested and everything seemed to work fine. Reinstalled in the car and my gauges all working properly. Not pegging to the extreme high reading. (Happy). Waited till dark to test the dash lights. Bench tested and they glowed bright as they still do now only problem is as I'm driving the headlights along with the dash lights flicker on and off rapidly. First guess is a ground issue. Any suggestions greatly appreciated. Really hoping not to have to take the instrument cluster out again. Ugh !!!

Are you saying the headlights AND dash lights are flickering? or just the dash lights shruggy

Yes the dash lights as well as the headlights are flickering at the same time.

Thought I'd start checking grounds and I just noticed that the ground strap from the block to the firewall is missing. By missing I mean it's not there and if I'm not mistaken they all had a ground strap from the factory. It's been like that for a very long time and I don't know why I haven't had an issue until lately.
Thanks again for any and all input.

Well yesterday I checked the connections at the bulkhead and everything there seemed good, no funky green stuff or anything. Next I checked the ground cable at the battery and it had quite a bit of corrosion so I cleaned the terminal (post) as well as the connecter. Sandpaper and file. At this point I also ran a ground from the negative post on the battery to the rad cradle. Then I checked the lights with the engine running and couldn't see any flickering. Had to wait until dark to be sure. So I went out for a drive after dark and after a 25 mile test drive not a flicker could be found. Also my temp. and oil pressure gauge seems to be reading a slight bit lower . They're now where I believe they used to be. Still have to add a ground strap from the engine to the firewall. Hopefully today.

Thanks to all for your help.
