Turbo 383 in a A-body Barracuda

I had to use the small lights they didn't leave any room on the backside of the dash on mine as it was i had to epoxy them in no room for even the nuts

i was also thinking like you to put the AEM gauge in the engine bay that might look good but it would sure make it easier to tune also

Yeah. Louis' idea is cool but the AEM isn't a sealed piece. The extreme heat and elements would most likely wreck it. Thats why I didn't buy the Innovate setup since the module was to be mounted under the hood. I read that it caused issues being out there in the heat and elements.

Another idea! I forget the actual size but get the correct holesaw and install the gauge facing the engine compartment in the firewall from the inside of the car. Get a tube of urethane and glue a piece of tempered glass or acrylic then mount the gauge. You could see it in the engine compartment but the gauge/module would be safe inside the car! Maybe over where the blower motor used to be??

I have flush mounted taillights in rollpans similar to this method with acrylic.
