50G:
Don't know about the 55 1st cross brace. The braces on the 52 are rods with flattened ends that bolt in. If I have to move them or make new ones it shouldn't be that difficultThere are literally a hundred different sizes of electric pusher fans. I am going to use a Zirgo because the motor is replaceable. Will also use a Dakota Digital controller which will work of the same sending unit as an electrical gauge. If you're going to use a mechanical gauge it shouldn't be too difficult to use fittings to plumb up and arrangement for both the fan sensor and the mechanical temp gauge.
