I'm working on a 1976 D100 (3.90 and a 5 speed) and would like to put in Dutra Duals in. I did find them at Laysons.com for $535 plus a core. Are they worth it? This is not a race truck, I like the idea of duals and it might help give it a little more power. Laysons mentions that there is a clearance issue with 80's A/C, just what I was hoping to add (better compressor). Has anyone dealt with this and if so how bad was it? I think I know what bracket needs to modified but I'm not sure. Thanks.

Why go to Layson's when you can PM Doc (Doug Dutra) here on the board and get them direct?

Hopefully a truck guy will chime in about the fitment with the A/C.

In addition to working directly with Doug Dutra, you would do well contacting CharrlieS on this forum. He can probably give A/C compressor advice.

I installed Dutra Duals on my '66 Dart slant six. I had to build one simple bracket from the rear of the compressor mount to the left engine mount. It was a simple build just to clear the front Dutra exhaust manifold runner. I suspect you could use the original truck A/C compressor bracket and just make a new rear brace. Don't try to leave that brace out as the main compressor mount may wiggle around and work-harden the steel. That rear bracket is important.
