After market dash cluster

You won't find one that doesn't require cutting the dash frame. All the aftermarket ones are based on the larger "Rally" sized dash frame openings.

Reason being is the metal opening is too small as is the gauge housing, you'd need tiny gauges to fit in there. On my 69 I was planning to used shallow depth gauges from SpeedHut and move them forward to clear the metal dash. But, I have a 3d printer so I can make what I want and graph it to a stock gauge frame.
