I ended up making a set of Diy led turn signals for my 1970 C30. I needed a way to make more room behind the turn signal housings to clear my cummins intercooler. The intercooler mounting brackets where hitting the turn signal bulb sockets. At first I tried using a set of sockets from a 1990s mazda that I had laying around. They were a little more low profile but they were still too long.

I ended up ordering a set of cheap led Surface Mount Oval Amber Turn Signal lights for a truck or trailer. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I started bending the black housing away from the clear lense with my hands, the lense if just glued on. Once it started to separate I went in with a flat head and popped the lense off.

I then trimmed the black bousing to fit in the turn signals.

I ended up putting the turn signal lense from the c30 in the mill and milled out a little bit of the lense to fit the leds as the two outer leds are just a little two wide to fit in the lense. You could do the same with a dremel or a grinder.

Its sits flush in the lense now.

I trimmed the second one a little bit better.

I'm just going to connect my stock connecter to the lights. you can see how much room I have now the stock bulb sockets stuck out like a inch and a half.

If you wanted to make it plug and play you could get a set of 2057 or 1157 Male Head Extension Connector Plug Socket with Wire Harness and make them plug and play.

I plan on getting a set of new lenses as mine are the originals and one is cracked. After I do that I plan on apoxing them in to make them a bit more waterproof. At the moment they just have tape on the back. They still use the stock seal but mine lenses had dirt in them when I took them off.
