For those who are interessed in fitting a flexiride axle
to your boler
The only thing needed is a shim (square tubing 2in x 2in ) between the existing support to clear the floor + you will have to move the axle
forward 1.75in (measure from the front of the square tubing to the end of the floor = 0.25in for the tubing being 2.5in (vs 2.0in) and because of the arm being 4.5in (vs 6.0in).
let me know if you have questions
