Stanglover,RC92234, may I ask where you bought your LED's? It could be that if you bought cheapo bulbs off good ol' epay, they are not good. I learned this lesson early on when I started to convert all my lights to LED/SMD's. That's when I found Bill at HiPoParts.com and he helped solve the issues with expert knowledge and excellent parts.
On the dash turn signal indicators, you either have one bulb in backwards, a bad circuit board connection, or the wrong bulb type. It is possible that the printed circuit board is bad as well. As said, I'm no electrical expert by a long shot, but I had issues with this as well, just not as bad. My car has idiot lights, so there is ONE BULB that MUST remain an incandescent #94 at that is at the ALT position. This is critical!! (it's the only non LED bulb on my car anywhere). I suggest start with one issue, figure that our and move to the next.
I realize 73 wiring may be a lot different to the 71/72's, but in general, I think the principle is the same. Good luck, hope you get it sorted soon.
Question concering your LED dash lights; I've converted my 72 dash to LED lights with excellent results EXCEPT the lighter, wiper and headlight bezel LED bulbs (different size bulb compared to dash bulbs) will not illuminate. If I put the stock incandescent back in the three bezel lights are fine. The polarity was good when I tried the LED bulbs. Did you incounter this non illuminating issue with your LED conversion??
