I've had Mark do the custom V8 tach for the Alien.
It plugged right in to my MSD 6A. Nice custom face with my choice of design. I'm very happy with the outcome.
He has also done a custom tach for the (Shealey) Sandy's 1959 Austin Healey. I insalled a Suzuki Swift engine in the car. The factory tach was a old school cable drive unit. He converted the guts to work with a modern HEI ignition. The tach looks untouched. The original patina is completely intacked. This is very important to me. I don't want to look at the dash and see an odd gauge.
Since I started installing the dash I realized the 5 speed Samurai transmission doesn't have a cable drive speedometer. I just sent Mark Sandy's speedometer. He is going to install electronic guts in the stock housing and retain the stock face and needle.
I'm really fussy about how the gauges look. I was very worried the Healey tach would look messed with. I'm extremely happy with the outcome of this gauge. Mark has a passion for the challange. I would use him again and I will continue to use his service.
