Re: ? diff in cal-trac vs slapper bar ?
The Check Mate cars used a floater with a heim joint attached to a bracket bolted to front perch bolt holes,,,those cars would hook on a skating rink,,the real beauty of that set up was the spring only held up the car,,not used to propel the car,,,the ABSOLUTE ULTIMATE in traction devices,,no one ever had a "A" car quicker in 60 feet with any consistency,,,period
